y-1=3x-12
Use the distributive property to multiply 3 by x-4.
3x-12=y-1
Swap sides so that all variable terms are on the left hand side.
3x=y-1+12
Add 12 to both sides.
3x=y+11
Add -1 and 12 to get 11.
\frac{3x}{3}=\frac{y+11}{3}
Divide both sides by 3.
x=\frac{y+11}{3}
Dividing by 3 undoes the multiplication by 3.
y-1=3x-12
Use the distributive property to multiply 3 by x-4.
y=3x-12+1
Add 1 to both sides.
y=3x-11
Add -12 and 1 to get -11.
