hx=x^{2}an
Multiply x and x to get x^{2}.
x^{2}an=hx
Swap sides so that all variable terms are on the left hand side.
nx^{2}a=hx
The equation is in standard form.
\frac{nx^{2}a}{nx^{2}}=\frac{hx}{nx^{2}}
Divide both sides by x^{2}n.
a=\frac{hx}{nx^{2}}
Dividing by x^{2}n undoes the multiplication by x^{2}n.
a=\frac{h}{nx}
Divide hx by x^{2}n.
hx=x^{2}an
Multiply x and x to get x^{2}.
xh=anx^{2}
The equation is in standard form.
\frac{xh}{x}=\frac{anx^{2}}{x}
Divide both sides by x.
h=\frac{anx^{2}}{x}
Dividing by x undoes the multiplication by x.
h=anx
Divide x^{2}an by x.
hx=x^{2}an
Multiply x and x to get x^{2}.
x^{2}an=hx
Swap sides so that all variable terms are on the left hand side.
