This is basic algebra. We want to get rid of all multiplication/division to the term (b1+b2)
You start with
Multiply both sides by 2 and divide both sides by h and get:

Subtract over b2 and your answer is:

(Note: if you want both sides under the same denominator and make it seem neater, you can also multiply -b2 by which equals 1. This gives you . However, they are equivalent and it doesn't matter which answer you use.)
