Answer:
x = -2, y = -1
Explanations:
The system of equations is:
8x - 7y = -9...................(1)
-3x + 4y = 2.....................(2)
Multiply equation (1) by 3 and multiply equation (2) by 8
24x - 21y = -27...........(3)
-24x + 32y = 16.............(4)
Add equations (3) and (4)
11y = -11
y = -11/11
y = -1
Substitute the value of y into equation (1)
8x - 7(-1) = -9
8x + 7 = -9
8x = -9 - 7
8x = -16
x = -16/8
x = -2
x = -2, y = -1
