2x-3=1
Square both sides of the equation.
2x-3-\left(-3\right)=1-\left(-3\right)
Add 3 to both sides of the equation.
2x=1-\left(-3\right)
Subtracting -3 from itself leaves 0.
2x=4
Subtract -3 from 1.
\frac{2x}{2}=\frac{4}{2}
Divide both sides by 2.
x=\frac{4}{2}
Dividing by 2 undoes the multiplication by 2.
x=2
Divide 4 by 2.
