Simplify the following expression:

2x − 2y + 5z − 2x − y + 3z (1 point)


x − 3y + 8z
2x − 2y + 8z
3y + 8z
−3y + 8z

My answer is A

Answer 1

wrong.....the 2x's cancel out..it is not A

Answer 2

2x − 2y + 5z − 2x − y + 3z
2X − 2y + 5z -2X − y + 3z (2x-2x, that's just 0)
− 2y + 5z − y + 3z (-2y-y, that's -3y)
-3y+5z+3z (5z+3z, that's 8z)
-3y+8z, D
