Equation solving
We are given the formula
[tex]h=\frac{2A}{b}[/tex]We need to solve the formula for b.
The formula needs to be expressed in such a way b is isolated at the left side
To do that, we'll do some basic operations as needed
First, we multiply by b
[tex]h\cdot b=\frac{2A}{b}\cdot b[/tex]Simplifying the right side:
[tex]h\cdot b=2A[/tex]Dividing by h:
[tex]b=\frac{2A}{h}[/tex]
