\sqrt{2x-1}=0
Swap sides so that all variable terms are on the left hand side.
2x-1=0
Square both sides of the equation.
2x-1-\left(-1\right)=-\left(-1\right)
Add 1 to both sides of the equation.
2x=-\left(-1\right)
Subtracting -1 from itself leaves 0.
2x=1
Subtract -1 from 0.
\frac{2x}{2}=\frac{1}{2}
Divide both sides by 2.
x=\frac{1}{2}
Dividing by 2 undoes the multiplication by 2.
