18%2B2n=4n-9 Start with the given equation.


2n=4n-9-18 Subtract 18 from both sides.


2n-4n=-9-18 Subtract 4n from both sides.


-2n=-9-18 Combine like terms on the left side.


-2n=-27 Combine like terms on the right side.


n=%28-27%29%2F%28-2%29 Divide both sides by -2 to isolate n.


n=27%2F2 Reduce.

Answer:

So the solution is n=27%2F2
