3%281%2B4n%29-2%285n-3%29=25 Start with the given equation.


3%2B12n-10n%2B6=25 Distribute.


2n%2B9=25 Combine like terms on the left side.


2n=25-9 Subtract 9 from both sides.


2n=16 Combine like terms on the right side.


n=%2816%29%2F%282%29 Divide both sides by 2 to isolate n.


n=8 Reduce.

Answer:

So the solution is n=8
