Question

Simplify the following expression.

2x - 2y + 5z - 2x - y + 3z

A.) x - 3y + 8z

b.) 2x - 2y + 8z

c.) 3y + 8z

d.) -3y + 8z

Answer 1

im not good with this whole problem. i tried solving it again,and again and im fruterared because i have no idea.

Answer 2

the first thing you should try is to put factors with common variables next to each other
so
2x - 2y + 5z - 2x - y + 3z would become 2x -2x -2y -y +5z +3z
this makes the problem easier to look at

Answer 3

next, combine factors with common variables.
2x -2x -2y -y +5z +3z
the 2x -2x = 0
the -2y -y = -3y
and the 5z +3z = 8z
so your answer is 0 -3y +8z or just -3y+8z
