2x_{3}x=13
Swap sides so that all variable terms are on the left hand side.
\frac{2x_{3}x}{2x_{3}}=\frac{13}{2x_{3}}
Divide both sides by 2x_{3}.
x=\frac{13}{2x_{3}}
Dividing by 2x_{3} undoes the multiplication by 2x_{3}.
2x_{3}x=13
Swap sides so that all variable terms are on the left hand side.
2xx_{3}=13
The equation is in standard form.
\frac{2xx_{3}}{2x}=\frac{13}{2x}
Divide both sides by 2x.
x_{3}=\frac{13}{2x}
Dividing by 2x undoes the multiplication by 2x.
