To solve for y you have to get y by itself. To do that, you use inverse operations. The inverse of addition is subtraction and inverse of multiplication is division.

-4x - 10 = - 2y Divide by - 2 to get y alone. What you do to one side of the

:-2 : - 2 equation, you must do to the other.

-2x - 5 = y

So the answer is b, y=-2x-5
