Solve for k
k=\frac{1-2h^{2}}{3}
Solve for h
h=\frac{\sqrt{2-6k}}{2}
h=-\frac{\sqrt{2-6k}}{2}\text{, }k\leq \frac{1}{3}

3k-1=-2h^{2}
Subtract 2h^{2} from both sides. Anything subtracted from zero gives its negation.
3k=-2h^{2}+1
Add 1 to both sides.
3k=1-2h^{2}
The equation is in standard form.
\frac{3k}{3}=\frac{1-2h^{2}}{3}
Divide both sides by 3.
k=\frac{1-2h^{2}}{3}
Dividing by 3 undoes the multiplication by 3.
