I ran this through an equation solver and it it tells me x = 2 only?

The way it is written is x+sqrt(11-x)= 5 x+ sqrt sign11-x = 5 the x is under the root sign then = 5 Would this still have the same conclusion? 2,7, or just 2 ?

I have a question regarding this problem below? I noticed it in an eariler post, and have come to figure that my text book has it like this? What would be the solution for this? x+sqrt(11-x)= 5 x = 2? OR 2,7? OR NO solution? I say x = 2 only? Any Thoughts?
