Answer:

x = -1 and y = -3

Step-by-step explanation:

The given equations are :

2x+3y= -11 ...(1)

8x -2y= -2​​ ...(2)

We need to solve the equations.

Multiply equation (1) by 4.

8x+12y= -44 ...(3)

Subtract equation (2) from (3).

8x+12y-(8x -2y) = -44-(-2)

8x+12y-8x +2y = -42

14y = -42

y = -3

Put the value of y in equation (2).

8x -2(-3)= -2​​

8x+6 = -2

8x = -8

x = -1

So, the values of x and y are -1 and -3 respectively.
