well, I'd say that it's
3/7+2-√7-3
Insert parentheses as need for proper evaluation!

there's nothing to solve. Just evaluate the expression. I tend to think that you meant
3/(x+2) - √(x+3)
but it's hard to say due to your carelessness with parentheses. If I got it right, then it just evaluates to
3/(7+2)-√(7-3) = 3/9 - √4 = 1/3 + 2 = 7/3
In the future, if there's any possible confusion about order of operations, be sure to use parens to avoid misunderstandings.
