To eliminate the fraction, multiply by 2 both sides of the equation. This gives,

2A = h x (b1 + b2)

Then, divide both the left hand and the right hand side of the equation by the variable h.

2A / h = b1 + b2

Next, subtract b1 from both sides,

(2A / h) - b1 = b2

Rearranging the equation,

b2 = (2A/h) - b1
