okay I re-did the problem....so the square root of (x-7) + square root of x = 4.
so I squared both sides to get x-7+x=16.
simplify: 2x-7=16
add 7 to both sides 2x=23
divide each side by 2 and x=11.5
did i get it?

Hello,
. Square both sides of the equation:
. Isolate the square-root on one side of the equation:
