Notice that there are 3 terms on the right hand side. You want to isolate b in order to solve for it.

Explanation:

I find it less confusing to place term containing the variable you want on the left hand side. (As long as it is positive).

#a + b + c = P#
To isolate #b# subtract #a# and #c# from both sides

#b = P - a - c#
