Answer 1

To solve for a variable means to isolate the variable on one side of the equation.
NOTE: We can write (1/2)(bh) as one fraction like this (bh/2). They mean the same thing.
We now have this:
a = (bh/2)
We multiply both sides of the fractional equation by 2. This is done to remove the fraction.


Doing this we now have a linear equation:
2a = bh
We now divide both sides of the equation by h to find the value of b.
Final answer:
(2a/h) = b

Answer 2

make b the subject of your formula by first eliminating the fraction by multiplying boths sides by 2, so now you have
2A=bh
eliminate h so you have b left
b=(2A)/h
