1
00:00:02,320 --> 00:00:03,460
OK.

2
00:00:03,890 --> 00:00:07,270
Now we are taking a linear equations.

3
00:00:07,280 --> 00:00:15,350
So the court for the linear equations while their solution just like I would write is equal to occlusion

4
00:00:15,440 --> 00:00:21,500
one coefficient occlusion to coefficient and occasion 3 coefficient.

5
00:00:21,680 --> 00:00:30,890
Okay just like X plus two Y is equal to one two x plus y is equal to three for X plus Y is equal to

6
00:00:30,890 --> 00:00:31,440
fly.

7
00:00:31,670 --> 00:00:34,280
These are pretty linear additions.

8
00:00:34,280 --> 00:00:40,830
What we will do inside us get getting backwards you will write the accretion coefficient of equation

9
00:00:40,850 --> 00:00:42,110
1.

10
00:00:42,390 --> 00:00:42,650
Okay.

11
00:00:42,650 --> 00:00:48,270
Then you will insert the semicolons occasion to coefficient.

12
00:00:48,290 --> 00:00:49,100
Okay.

13
00:00:49,340 --> 00:00:55,220
And again you will insert the semicolons and occlusion pity coefficient.

14
00:00:55,220 --> 00:00:56,700
You write or okay.

15
00:00:57,040 --> 00:01:02,330
And the constant means just like 2 x plus 1 is equal to 2.

16
00:01:02,390 --> 00:01:05,390
So you will write 2 over here okay.

17
00:01:05,470 --> 00:01:07,790
Example x plus four is equal to five.

18
00:01:07,850 --> 00:01:13,690
You will write five or hit and tada Gwich'in is six x plus 9 y is equal to 7.

19
00:01:13,700 --> 00:01:16,070
You will write 7 0 here okay.

20
00:01:16,340 --> 00:01:22,130
And if you want to want the value of X Y is X Y.

21
00:01:22,190 --> 00:01:27,500
If there are two variables x and y there are three variables then you can also find the value of three

22
00:01:27,500 --> 00:01:28,580
variables.

23
00:01:28,580 --> 00:01:32,220
So the onset can be obtained by a minus B.

24
00:01:32,570 --> 00:01:35,850
Okay so this key word symbol will be used.

25
00:01:36,140 --> 00:01:44,570
A slash B E slash B and semicolons of the best thing the enter button you will find the value of x and

26
00:01:44,570 --> 00:01:45,260
y.

27
00:01:45,260 --> 00:01:50,150
If there are two variables and if they are three variables of course you can find the variable three

28
00:01:50,150 --> 00:01:57,670
variables x y and c not consider some linear equations.

29
00:01:57,670 --> 00:02:02,500
The code for linear occasion here will solve linear equation.

30
00:02:02,710 --> 00:02:12,010
The coefficient of lean in the equations are 1 to wipe and it will be separated by semicolons 4 5 7.

31
00:02:12,010 --> 00:02:22,140
This is the second occasion was a question our 4 5 7 and part of the equation whose chords are 2 3 4.

32
00:02:22,210 --> 00:02:28,060
After entering semicolons something is going wrong.

33
00:02:28,270 --> 00:02:34,970
It means we have internal the above numbers a little bit wrong.

34
00:02:35,390 --> 00:02:38,600
Yes there should be semicolons over here.

35
00:02:38,600 --> 00:02:41,080
Yes this is the mistake.

36
00:02:41,110 --> 00:02:41,460
Okay.

37
00:02:41,480 --> 00:02:42,070
No.

38
00:02:42,080 --> 00:02:45,600
1 2 3 semicolons again.

39
00:02:45,980 --> 00:02:49,540
4 5 6 semicolons.

40
00:02:51,760 --> 00:02:57,000
And 1 2 4 3 okay.

41
00:02:57,010 --> 00:03:00,890
No we will insert that interval done.

42
00:03:01,440 --> 00:03:14,170
Yes it is working and B is equal to this like X plus two Y plus three zi is equal to 2 and 4 x plus

43
00:03:14,170 --> 00:03:16,650
5 y plus 6 is equal to 3.

44
00:03:16,920 --> 00:03:19,990
An x plus four y plus three z is equal to four.

45
00:03:20,620 --> 00:03:21,190
Yes.

46
00:03:21,190 --> 00:03:25,070
So this is the equal Min constant will be written.

47
00:03:25,080 --> 00:03:28,070
B Okay so Answer.

48
00:03:28,070 --> 00:03:35,620
Answer the value of X and Y can be formed by writing ONS is equal to S slash B so the value of x is

49
00:03:35,710 --> 00:03:41,960
is minus one point something in the value of y is one point something and the value of zis zero point

50
00:03:41,980 --> 00:03:42,800
three something.

51
00:03:42,860 --> 00:03:49,130
Okay now we are talking again and other Yes.

52
00:03:49,150 --> 00:03:57,010
X plus two Y last three Z plus 40 okay is equal to something.

53
00:03:57,310 --> 00:04:07,010
Yes three x plus four y plus five Z plus two days and two x plus four y plus five Z plus two T.

54
00:04:07,030 --> 00:04:10,580
Yes plus two T.

55
00:04:10,990 --> 00:04:16,490
And this will be written between the square brackets.

56
00:04:16,510 --> 00:04:16,970
Okay.

57
00:04:17,020 --> 00:04:23,140
No it will be separated at the end with right.

58
00:04:23,140 --> 00:04:24,970
We will write the semicolons.

59
00:04:24,970 --> 00:04:26,440
Okay.

60
00:04:26,440 --> 00:04:26,740
No.

61
00:04:27,130 --> 00:04:27,700
Yes.

62
00:04:27,700 --> 00:04:35,020
We are taking another occasion three x plus four y plus please Z plus two D I guess so.

63
00:04:35,020 --> 00:04:36,750
One two three four.

64
00:04:36,820 --> 00:04:38,240
These are four occasions here.

65
00:04:38,350 --> 00:04:42,020
I would write B is equal to the constant.

66
00:04:42,040 --> 00:04:44,220
Of course there are four constant.

67
00:04:44,440 --> 00:04:55,320
Yes and the first constant we are taking over here it is four occasions for constant one and semicolons

68
00:04:56,070 --> 00:05:09,420
then semicolons twenty yes again semicolons thirty and semicolons there should be 40 otherwise it will

69
00:05:09,420 --> 00:05:09,830
be.

70
00:05:10,170 --> 00:05:15,110
Yes semicolon forty yes.

71
00:05:15,240 --> 00:05:26,300
No of course at the end we will insert semicolons and here the right answer is equal to is slash B and

72
00:05:26,290 --> 00:05:30,200
a press the interpreter will find the value of x y z is empty.

73
00:05:30,240 --> 00:05:35,740
So these are the values of x y z and D X equals minus 10.

74
00:05:35,840 --> 00:05:36,740
Is it called 25.

75
00:05:36,750 --> 00:05:37,470
Just like that.
