Question

HELP MEDAL AND FAN!!!!!!!!!!
Simplify: –7(x – y – 2z)

Answer 1

@Duck.

Answer 2

multiply -7 times each term inside the parens
can you do that ?

Answer 3

Yes I think, so. Let me take a few minutes and I will tell you what I got.

Answer 4

btw, it may be less confusing if you first write it as
\[ –7(x + (–y) + (–2z))\]

Answer 5

I got –7x + 7y + 14z

Answer 6

yes

and it is a good idea to remember you can "undo" that and change
–7x + 7y + 14z = -7(x -y -2z)

algebra is learning how to change from one to another (or back)

Answer 7

Okay thank you, so much.
