3x+1=25
Square both sides of the equation.
3x+1-1=25-1
Subtract 1 from both sides of the equation.
3x=25-1
Subtracting 1 from itself leaves 0.
3x=24
Subtract 1 from 25.
\frac{3x}{3}=\frac{24}{3}
Divide both sides by 3.
x=\frac{24}{3}
Dividing by 3 undoes the multiplication by 3.
x=8
Divide 24 by 3.
