first off, I like to circle to common ones... so I first circle the two x's. Since we are subtracting, it would be x-x which is 0. Thenm i circled the 2y's. It would be

2y - (-2Y) aka 2y +2y which is 4y. Then, -2z-2z which is -4z.

it would be 0+4y-4z and you obviously do not need the zero so the guy up there, visoth is right.
