Solve formula for indicated variable

[gaminlegend38]

This is probably pretty simple for most of you but I don't have a clue how to do these. I guess that's what I get for taking bad notes.

V=s²+½sh; solve for h...

I just want to be guided along.

Thanks for the help.

Subtract s² from both sides. Multiply through by 2. Divide off the remaining s.

Disagree, Eliz; first step is CHANGE s to a non-number-like-letter(!):
V = a^2 + ah/2

...I often use 5 instead of S when trying to solve... :roll:
