Question 841192: 6n-12=n+3
Okay, so I have no idea on which side to do first...
When I did the right first I got 15 over 6.
I don't think that's correct.
And when I started with the left I ended up with -24
I checked and both are incorrect.
Help? Thanks !

6n-12=n%2B3 Start with the given equation.



6n=n%2B3%2B12 Add 12 to both sides.



6n-n=3%2B12 Subtract n from both sides.



5n=3%2B12 Combine like terms on the left side.



5n=15 Combine like terms on the right side.



n=%2815%29%2F%285%29 Divide both sides by 5 to isolate n.



n=3 Reduce.

Answer:

So the solution is n=3
