x = 4y ---> x - 4y = 0 Let's multiply this equation by (-2)

-2x + 8y = 0

+

2x - 3y = - 15

0 + 5y = -15 ----> y = -3

x = 4 * (-3) -----> x = -12

Answer: **(-12, -3)**

Hi Amber,

try the methods that we all showed you in your previous questions. I can help you if you get stuck. To get you started try this

2x-3y=-15

x-4y = 0

hope this helps!
