Question

a=1/2bh how do you solve for b?

Answer 1

a = 1/2bh Solve for b.
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
