Please answer the question from the attachment.

If y = 4x then you'd input that information into your equation making: 3x-4x = 1 The correct solution is: 3(-1)-4(-1) = 1

y = 4x           .....(a) 3x - y = 1.    ......(b) Substitute y = 4x in (a) into (b) 3x - y = 1......(b) 3x - 4x = 1 -x = 1 x = -1 Recall, y = 4x ........(a) y = 4*(-1) y = -4. Therefore, x = -1, and y = -4.
