question isn't quite clear...
if it is a=(1/2)hb, then you would need to isolate the b. As is, it is multiplied by an h and a 1/2, so you would need to divide (inverse opperation) both sides by h and 1/2. remember that dividing by 1/2 is same as multiplying by 2.
a=(1/2)hb
(2a)/h=b --> your answer
now...if this is supposed to be a=1/2h(B-b) i would move the 1/2h to the other side first, just as we did above.
a=1/2h(B-b)
(2a)/h=B-b --> now to get B by itself, you add b to both sides
[(2a)/h] + b = B --> answer
hope that helps...if not, might want to retype the problem.

If you made a typo and the equation is "a=1/2h(B-b)" I'm reading it as "a" equals one half "h" times the value of Big "B" minus little "b"
1. Multiply both sides by 2
2a = h(B-b)
2. Divide both by "h"
2a/h = B - b
3. Add "b" to both
2a/h + b = B

it appears to be part of the equation for area of a triangle
a=1/2bh
