My choice would be 2
Is that correct
I squared both sides and came out with 7x = 9
and then x = 2
Thank you for taking the time to check this

5 is correct for
sqrt(2x + 15) = x
Notice that parentheses are required to show an expression correctly.
For the second one, would you like to double check:
7x = 9,
x=?
or
does
7  2 = 9? 
Should it be (2) instead of positive 2
