Question

Solve the system of equations.
8x + 5y = 24
y = -4x
x =
y =

Answer 1

x = -2

y = 8

Explanation:

8x + 5y = 24

y = -4x

8x + 5 (-4x) = 24 (Substitute y value)

8x - 20x = 24 (Multiply)

-12x = 24 (Combine like terms and divide)

x = -2

y = -4 (-2) (Substitute x value. Multiply)

y = 8
