Answer:

2A/h - b1 =  b2

Step-by-step explanation:

A = 1/2 h ( b1+b2)  

We want to solve for b2

Multiply each side by 2

2A = 2* 1/2 h ( b1+b2)  

2A =  h ( b1+b2)  

Divide each side by h

2A / h =  h/h ( b1+b2)  

2A / h =   b1+b2

Subtract b1 from each side

2A/h - b1 = b1 + b2 -b1

2A/h - b1 =  b2
