Math, Please Help! I don't understand!

Please help me! I don't understand how to solve.
Solve each equation for the given variable.
37. x/a  1 = y/b for x
39. V = 1/3 * pi * r^2 * h for h
What do these equations mean? I am super confused. Please help.

37. Add 1 to both sides, then multiply that by a.
39. Multiply both sides by 3, then divide by π and r^2. 
PsyDAY, so is this correct for number 37?
37. x = a + ay/b
I need your help on 39. I'm stil1 not getting it.
