What is 3(8+6n)=6n-12

3(8 + 6n) = 6n - 12 equals n = -3.

First, expand. Your problem should look like: 24 + 18n = 6n - 12.
Second, subtract 6n from both sides. Your problem should look like: 24 + 18n - 6n = -12.
Third, simplify 24 + 18n - 6n to 24 + 12n. Your problem should look like: 24 + 12n = -12.
Fourth, subtract 24 from both sides. Your problem should look like: 12n = -12 - 24.
Fifth, simplify -12 - 24 to -36. Your problem should look like: 12n = -36.
Sixth, divide both sides by 12. Your problem should look like: n = - .
Seventh, simplify  to 3. Your problem should look like: n = -3, which is your answer.
