y-7=4x+4
Use the distributive property to multiply 4 by x+1.
4x+4=y-7
Swap sides so that all variable terms are on the left hand side.
4x=y-7-4
Subtract 4 from both sides.
4x=y-11
Subtract 4 from -7 to get -11.
\frac{4x}{4}=\frac{y-11}{4}
Divide both sides by 4.
x=\frac{y-11}{4}
Dividing by 4 undoes the multiplication by 4.
y-7=4x+4
Use the distributive property to multiply 4 by x+1.
y=4x+4+7
Add 7 to both sides.
y=4x+11
Add 4 and 7 to get 11.
