n+3=-3\left(m+1\right)-8
Multiply both sides of the equation by 2.
n+3=-3m-3-8
Use the distributive property to multiply -3 by m+1.
n+3=-3m-11
Subtract 8 from -3 to get -11.
-3m-11=n+3
Swap sides so that all variable terms are on the left hand side.
-3m=n+3+11
Add 11 to both sides.
-3m=n+14
Add 3 and 11 to get 14.
\frac{-3m}{-3}=\frac{n+14}{-3}
Divide both sides by -3.
m=\frac{n+14}{-3}
Dividing by -3 undoes the multiplication by -3.
m=\frac{-n-14}{3}
Divide n+14 by -3.
n+3=-3\left(m+1\right)-8
Multiply both sides of the equation by 2.
n+3=-3m-3-8
Use the distributive property to multiply -3 by m+1.
n+3=-3m-11
Subtract 8 from -3 to get -11.
n=-3m-11-3
Subtract 3 from both sides.
n=-3m-14
Subtract 3 from -11 to get -14.
