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.

  • Math, Please Help! I don't understand! -

    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.
