2ax=8
Add 8 to both sides. Anything plus zero gives itself.
2xa=8
The equation is in standard form.
\frac{2xa}{2x}=\frac{8}{2x}
Divide both sides by 2x.
a=\frac{8}{2x}
Dividing by 2x undoes the multiplication by 2x.
a=\frac{4}{x}
Divide 8 by 2x.
2ax=8
Add 8 to both sides. Anything plus zero gives itself.
\frac{2ax}{2a}=\frac{8}{2a}
Divide both sides by 2a.
x=\frac{8}{2a}
Dividing by 2a undoes the multiplication by 2a.
x=\frac{4}{a}
Divide 8 by 2a.
