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!
