-5x+y=-3
3x-8y=24

Substitution method. Solving for the first equation, because it's easy.

y=-3+5x

Plugin to the other equation.
3x-8(-3+5x)=24
Simplify: 3x+24-40x=24 (Remember, multiplying negatives makes it positive.)
Simplify: -37x + 24 = 24
Subtract: -37x = 24-24
-37x=0
x=0

Plug back into the first:
y=-3+5(0)
y=-3+0
y=-3

Option A
