y=12x+7
Multiply 3 and 4 to get 12.
12x+7=y
Swap sides so that all variable terms are on the left hand side.
12x=y-7
Subtract 7 from both sides.
\frac{12x}{12}=\frac{y-7}{12}
Divide both sides by 12.
x=\frac{y-7}{12}
Dividing by 12 undoes the multiplication by 12.
y=12x+7
Multiply 3 and 4 to get 12.
