1) A = (1/2h)(b1+b2)
2) A*2h = b1 + b2
3) A*2h - b2 = b1
4) b1 = 2Ah - b2

Hope this helps!!

now given no values for anything you need to get b1 alone on one side of equation. First multiply both sides by 2 to get rid of fraction giving you 2A = b1 + b2 and then subtract b2 from both sides. Gives you 2A - b2 = b1

A = Â½h(b1 + b2) (x 2)
2A = h(b1 + b2) (Ã· h)
2A/h = (b1 + b2) (- b2)
[2A/h] - b2 = b1
