3x_{2}x=12
The equation is in standard form.
\frac{3x_{2}x}{3x_{2}}=\frac{12}{3x_{2}}
Divide both sides by 3x_{2}.
x=\frac{12}{3x_{2}}
Dividing by 3x_{2} undoes the multiplication by 3x_{2}.
x=\frac{4}{x_{2}}
Divide 12 by 3x_{2}.
3xx_{2}=12
The equation is in standard form.
\frac{3xx_{2}}{3x}=\frac{12}{3x}
Divide both sides by 3x.
x_{2}=\frac{12}{3x}
Dividing by 3x undoes the multiplication by 3x.
x_{2}=\frac{4}{x}
Divide 12 by 3x.
