Question

Simplify the following expression.
2x − 2y + 3z − 2x − y + 2z = ?

4x − 3y + 5z

−2y − 3y + 5z

−2x − 3y + 6z

−3y + 5z

Answer 1

\[\huge{2x-2y+3z-2x-y+2z}\]
\[\huge{2x-2x-2y-y+3z+2z}\]
Can you solve this now ?

Answer 2

easy first collect the x's

Answer 3

combine like terms:
2x − 2y + 3z − 2x − y + 2z
2x -2x -2y - y + 3z + 2z

2x -2x cancel out each other

-2y - y = -3y

3z + 2z = 5z

so your answer is:
-3y +5z
