Answer:
Multiply each expression by the same number.
Step-by-step explanation:
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
