V=s^2 + 1/2sh, solve for H.

No idea, I'm completely stuck on this sort of thing. If someone could work it out so I could see how it's done, that would be lovely.

V = s^2 + 1/2sh

Reorder so common terms are on one side.

s^2 + (sh) / 2 = v

Subtract s^2 from both sides.

(sh) / 2 = - s^2 + v

Multiply both sides of the equation by 2.

sh = - s^2 * 2 + v * 2

Simplify each term.

sh = - 2s^2 + 2v

Divide each term by s and simplify.

h = - 2s + (2v) / s
