What's y=4x-2

3x+2y=-4

X=0

Y=-2

Multiply the top equation by - 2 to get - 2y=-8x+4

Isolate 2y on the bottom by subtracting 3x from both sides to get 2y = - 4 - 3x

Add the two equations get 0=-11x so x = 0

Solve for y by plugging zero into one of the equations to get y=4 (0) - 2 to find the y = - 2

y=4 (0) - 2
