3x-13=25
Square both sides of the equation.
3x-13-\left(-13\right)=25-\left(-13\right)
Add 13 to both sides of the equation.
3x=25-\left(-13\right)
Subtracting -13 from itself leaves 0.
3x=38
Subtract -13 from 25.
\frac{3x}{3}=\frac{38}{3}
Divide both sides by 3.
x=\frac{38}{3}
Dividing by 3 undoes the multiplication by 3.
