Question

Solve for a: c(a+b)-d=f

Answer 1

Distribute the c so you get

Ca+cb-d=f

Then subtract cb from the first problem.

Ca-d=f-cb

Then add d from the first problem

Ca=f-cb+d

Then divide c from each side

Ca. =. F-cb+d
—— ————
C C


So you should get

A= f-cb+d/c

Answer 2

First simplify it, making it ca+cb-d=f. Then move cb and -d to the other side, which flips their signs, making the equation ca=f+d-cb. Then divide the left side by c to get rid of it and the right side to make it even, which gives you a=f+d-cb/c
