2x+1=25
Square both sides of the equation.
2x+1-1=25-1
Subtract 1 from both sides of the equation.
2x=25-1
Subtracting 1 from itself leaves 0.
2x=24
Subtract 1 from 25.
\frac{2x}{2}=\frac{24}{2}
Divide both sides by 2.
x=\frac{24}{2}
Dividing by 2 undoes the multiplication by 2.
x=12
Divide 24 by 2.
