Your text is not well written so one could guess you have sqrt(2x)+x=4, which would best appear .

Isolate the radical.


Square the equated members.


Simplify and solve.



and if you check you find both x=2 and x=8 will work.
x=2 OR x=8.

This appears to be . If so, the answer CANNOT be C, but: , instead.

Why don't you use parentheses, or provide info to make this problem less ambiguous? Is that so difficult?
