What we solve in mathematics are problems (well written) and equations, etc.
There is no equation here. There are three expressions enclosed in parentheses.
You do not SAY what these expressions represent.
(If they are measurements of angles in a single triangle, then one can solve for x. But you have not actually written a definitive question.)
