A=1/2H(B+b) Solve for H

Let's start by getting rid of the fraction.

Multiply both sides by 2 (whatever operation you do to one side of an equation you must do to the other side as well):

2(A) = 2[1/2H(B+b)]

2A = H(B+b)

Now divide both sides by (B+b) and end up with this:

2A/(B+b) = H

I hope this will help.
