3\times 3=n-4+2
Variable n cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 3n^{2}, the least common multiple of n^{2},3n^{2}.
9=n-4+2
Multiply 3 and 3 to get 9.
9=n-2
Add -4 and 2 to get -2.
n-2=9
Swap sides so that all variable terms are on the left hand side.
n=9+2
Add 2 to both sides.
n=11
Add 9 and 2 to get 11.
