-84=6+10n-20
Use the distributive property to multiply 5 by 2n-4.
-84=-14+10n
Subtract 20 from 6 to get -14.
-14+10n=-84
Swap sides so that all variable terms are on the left hand side.
10n=-84+14
Add 14 to both sides.
10n=-70
Add -84 and 14 to get -70.
n=\frac{-70}{10}
Divide both sides by 10.
n=-7
Divide -70 by 10 to get -7.
