4gh=v
Swap sides so that all variable terms are on the left hand side.
4hg=v
The equation is in standard form.
\frac{4hg}{4h}=\frac{v}{4h}
Divide both sides by 4h.
g=\frac{v}{4h}
Dividing by 4h undoes the multiplication by 4h.
4gh=v
Swap sides so that all variable terms are on the left hand side.
\frac{4gh}{4g}=\frac{v}{4g}
Divide both sides by 4g.
h=\frac{v}{4g}
Dividing by 4g undoes the multiplication by 4g.
