-x+4<=x 2x=>4 x>=2

dipankarstudy is correct. What you do is to square both sides of the equation in order to eliminate the square root and then solve the equation.

Actually, the solution is just 2<=x<=4. If x>4, then the left side is the square root of a negative number, which is not a real number.
