Question 54060: Can someone help me on this problem?
I need to solve this literal equation for the indicated variable as follows:
A = 1/2h (B + b) (for b) Area of a trapezoid
Thanks,

A = h (B + b) (for b)
:
Mult the equation by 2; gets rid of the denominator:
2A = h(B + b)
:
Divide both sides by h:
= B + b
:
Subtract B from both sides:
- B = b
