3x+10=64
Square both sides of the equation.
3x+10-10=64-10
Subtract 10 from both sides of the equation.
3x=64-10
Subtracting 10 from itself leaves 0.
3x=54
Subtract 10 from 64.
\frac{3x}{3}=\frac{54}{3}
Divide both sides by 3.
x=\frac{54}{3}
Dividing by 3 undoes the multiplication by 3.
x=18
Divide 54 by 3.
