y_{2}x=12-3
Subtract 3 from both sides.
y_{2}x=9
Subtract 3 from 12 to get 9.
\frac{y_{2}x}{y_{2}}=\frac{9}{y_{2}}
Divide both sides by y_{2}.
x=\frac{9}{y_{2}}
Dividing by y_{2} undoes the multiplication by y_{2}.
y_{2}x=12-3
Subtract 3 from both sides.
y_{2}x=9
Subtract 3 from 12 to get 9.
xy_{2}=9
The equation is in standard form.
\frac{xy_{2}}{x}=\frac{9}{x}
Divide both sides by x.
y_{2}=\frac{9}{x}
Dividing by x undoes the multiplication by x.
