3+x=12y
Swap sides so that all variable terms are on the left hand side.
x=12y-3
Subtract 3 from both sides.
12y=x+3
The equation is in standard form.
\frac{12y}{12}=\frac{x+3}{12}
Divide both sides by 12.
y=\frac{x+3}{12}
Dividing by 12 undoes the multiplication by 12.
y=\frac{x}{12}+\frac{1}{4}
Divide 3+x by 12.
