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.
