Question

What is ax + z = aw − y , for a?

Answer 1

You can do the following \[z+y=aw-ax\] notice I added y on both sides and subtracted ax from both sides, now you can factor out an a.

Answer 2

Any idea how?

Answer 3

No

Answer 4

Well yes

Answer 5

\[z+y=a(w-x)\] Notice since the left side both share an a

Answer 6

right side*

Answer 7

But how did you get z+y

Answer 8

and not -y-z

Answer 9

Oh I added +y instead of subtracting both sides by z just to make it look cleaner

Answer 10

But is subtracting both sides by z okay

Answer 11

Does that make sense?
