9H=3x
The equation is in standard form.
\frac{9H}{9}=\frac{3x}{9}
Divide both sides by 9.
H=\frac{3x}{9}
Dividing by 9 undoes the multiplication by 9.
H=\frac{x}{3}
Divide 3x by 9.
3x=9H
Swap sides so that all variable terms are on the left hand side.
\frac{3x}{3}=\frac{9H}{3}
Divide both sides by 3.
x=\frac{9H}{3}
Dividing by 3 undoes the multiplication by 3.
x=3H
Divide 9H by 3.
