Question

C=5p + 215 solve for P
Would it be (c-215)/5 = P or c/5 - 215 = P

Answer 1

The first one.

Answer 2

the first one :-) but if you wanted you could rewrite it:
(c-215)/5=P
c/ 5 - 215/5 = p
c/5 - 43 =P

Usually though you are expected to have a common denominator :-)

Answer 3

how do you know when to divide by just the first variable or both?

Answer 4

Always divide the whole side of the equation.
