-4
My choice would be 2
Is that correct-
I squared both sides and came out with 7-x = 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:
    7-x = 9,
    x=?

    or

    does
    7 - 2 = 9?
