6x-9=9
Square both sides of the equation.
6x-9-\left(-9\right)=9-\left(-9\right)
Add 9 to both sides of the equation.
6x=9-\left(-9\right)
Subtracting -9 from itself leaves 0.
6x=18
Subtract -9 from 9.
\frac{6x}{6}=\frac{18}{6}
Divide both sides by 6.
x=\frac{18}{6}
Dividing by 6 undoes the multiplication by 6.
x=3
Divide 18 by 6.
