-66=-6+3n-3
Use the distributive property to multiply n-1 by 3.
-66=-9+3n
Subtract 3 from -6 to get -9.
-9+3n=-66
Swap sides so that all variable terms are on the left hand side.
3n=-66+9
Add 9 to both sides.
3n=-57
Add -66 and 9 to get -57.
n=\frac{-57}{3}
Divide both sides by 3.
n=-19
Divide -57 by 3 to get -19.
