Question

30. Solve graphically
Solution
5x +y = 7 and 2x -2y=2​

Answer 1

Answer:

X=4/3 and y=1/3

Step-by-step explanation:

5x+y=7

2x-2y=2

First fall we use elimination method for this equation

So,

5x+y=7 * - 2

2x-2y=2

- 10x-2y=-14

2x-2y=2

Subtract both

So, - 12x = - 16

X=16/12=4/3

Put the value of x in equation 2

2*4/3 - 2y=2

8/3-2=2y

2/3=2y

y=1/3

I hope this will help you
