Answer:

Step-by-step explanation:

Given system of equations is,

8x + 10y = 120 -----(1)

x - y = -3 ------(2)

From the second equation,

x = y - 3 [Option A]

Now we substitute the value of x in equation (1) and solve for y,

8(y - 3) + 10y = 120

8y - 24 + 10y = 120

18y = 120 - 24

y = [tex]\frac{96}{18}[/tex] = 8

From equation (2)

x - 8 = -3

x = 8 - 3

x = 5
