n=8+4s-4
Use the distributive property to multiply 4 by s-1.
n=4+4s
Subtract 4 from 8 to get 4.
n=8+4s-4
Use the distributive property to multiply 4 by s-1.
n=4+4s
Subtract 4 from 8 to get 4.
4+4s=n
Swap sides so that all variable terms are on the left hand side.
4s=n-4
Subtract 4 from both sides.
\frac{4s}{4}=\frac{n-4}{4}
Divide both sides by 4.
s=\frac{n-4}{4}
Dividing by 4 undoes the multiplication by 4.
s=\frac{n}{4}-1
Divide n-4 by 4.
