Question

Simplify the following expression. 2x − 6y + 2z − 5x − 3y + 8z

Answer 1

Combine the like terms, that is terms with 'x' together, with 'y' together, and similarly for terms with 'z'.

Answer 2

so how do i do that every time i do i turns out wrong

Answer 3

Okay, just follow this:
2x - 6y + 2z − 5x − 3y + 8z

so I am combining like terms together:
(2x - 5x) + (2z + 8z) + (-6y - 3y)


Okay with this^?

Answer 4

yes so it would be -3x-3y+10z?

Answer 5

almooost there!! :)

-6y -3y = y(-6-3) = -9y actually

Answer 6

okay so its -3x-9y+10z?
