Answer:
A
Step-by-step explanation:
Start with variable x.
4x - 6y = 28
Substitute the variables for numbers.
4(1) - 6(-4) = 28
Solve the new equation
4 + -24 = 28
Move to the second equation with variable y.
8x - 4y = 24
Substitute variables
8(1) - 4(-4) = 24
Solve
8 - (-16) = 24
The answer is A, x = 1, y = -4
