Answer:

Explanation:

-4y - 3x = -11 (1)

x - 2y = 17 (2)
x = 17 + 2y

Substitute x value in (1)

-4y - 3(17 + 2y) = -11
-4y - 51 - 6y = -11
-10y - 51 = -11
-10y = -11 + 51
-10y = 40
y = 40/-10
y = -4

Substitute the y value in (2)

x - 2(-4) = 17
x + 8 = 17
x = 17 - 8
x = 9

Therefore, x = 9 and y = -4
