Answer:
[tex]B=\frac{2A}{h}-b[/tex]
Step-by-step explanation:
To solve this B needs to be isolated. First we must multiply both sides of the equation by 2 to get rid of the fraction on the left side. Next, divide both sides by h to get rid of the h on the left side. Finally, subtract b form both sides to get B by itself.
