Question

explain ans and also in graph

Answer 1

Given  : 2x + 3y = 10

3x - 12 = - 3y

To Find : Solve graphically

Solution:

2x + 3y = 10

3x - 12 = - 3y

2x + 3y = 10

x    y

-1     4

2     2

5      0

3x - 12 = - 3y

x     y

-1    5

0    4

1      3

2    2

3     1

4     0

x = 2 , y = 2 is the solution

2(2) + 3(2) = 10

3(2) - 12 = -3(2)

Similarly do others

x - 3y =  -7

4x + y  = 11

x = 2  , y = 3

x - 2y  = 0

3x - 4y  - 20 = 0

x = 20 , y = 10
