Without an equality sign, there is no equation, just an expression, so it can't be solved, only simplified, which it already is.

It's not equal to anything, so you can't solve for x. If it is equal to 0, then multiply both sides by 2x + 1, which just gets rid of it, and solve x + 1 = 0, which is just x = -1.
