Question

Simplify the following expression.
5x - 6y + 5z - x - 12y + 2z

I would add like terms right? @jim_thompson5910

Answer 1

First reorder the terms

Answer 2

you are correct unheard

Answer 3

so for instance, 5x and -x are like terms, which add to 5x + (-x) = 5x - x = 4x

Answer 4

I would start it out by reording like this 5x + -1x + -6y + -12y + 5z + 2z
and then combining like terms

Answer 5

4x+ -18y + 7z right?

Answer 6

and that can be written as 4x - 18y + 7z

Answer 7

so you got it
