If you distribute the negative sign on the left side of the equation, you get -x + y = x - y.

Moving the y on the right over to the left, you get -x + 2y = x.

Moving the negative x on the left over to the right, you get 2y = 2x.

Dividing both sides by 2, you get y = x.

Therefore, the answer is choice C - the two quantities are equal.

or, \(-x+y = x-y\)
or, \(2y = 2x\)
or, \(y = x\)
