Please Solve: x+sqrt11−x = 5

Question

I do not think there is a solution but here are the choices

A. 2
B. 7
C. 2, 7
D. No solution

Answer 1

Just checking answers, the first works. The second works (if you use the negative square root).

So, IMO, c is the best answer.

Answer 2

You sure I get no solution for this probelm, can you show me how C. 2, 7 works? Thanks!

Answer 3

x+sqrt11−x = 5

try 2
2 + sqrt (9) = 2+3 = 5

try 7
7 + sqrt (4) = 7+2 or 7-2 = 9 or 5

Answer 4

So what does all this mean? I still get no solution but Mr. Bob tells me it's 2,7? So which one would it be? I am confused and have 5 more like this...Please explain further.

C. 2, 7
D. No solution
