the squareroot of -12 + 2x = the squareroot of 3x+23
(2x-12)^1/2 = (3x+23)^1/2
Take the square on both sides of the equation
2x-12=3x+23
2x-3x=23+12
-x=35
x=-35

        The solution in the post by @mananth is fatally wrong.
        See my correct solution below.


Our starting equation is

    sqrt%282x-12%29 = sqrt%283x%2B23%29.


Take the square on both sides of the equation

    2x - 12  = 3x + 23

    -12 - 23 = 3x - 2x

       x    =    -35


But x = -35 makes the expression  2x-12  negative under the square root in the left side of the original equation.


So, we conclude that given equation has no real solution.

Solved correctly.
