Question

Solve the system of equations

y = -8x

y = -5x - 9

Hint: replace "y" with an equivalent x term

( , )

Answer 1

Because both answers equal y, we can set them equal to each other. So, -8x=-5x-9. Add five over to get -3x=-9. Divide and x=3. Then plug 3 in to solve for y. -8(3)=24. The ordered pair is (3,24).
