You can
put this solution on YOUR website!No, you can't! You can't solve for n, unless you have an EQUATION. This is just an expression. You can SIMPLIFY an EXPRESSION (or use the distributive property to remove the parentheses):

can be expanded and written as

.
Or, if the original problem is an EQUATION, like

, then you can SOLVE the equation, by saying that

or

, so
I'm not sure what you meant, but that should cover it either way, right?
