10x-12=144
Square both sides of the equation.
10x-12-\left(-12\right)=144-\left(-12\right)
Add 12 to both sides of the equation.
10x=144-\left(-12\right)
Subtracting -12 from itself leaves 0.
10x=156
Subtract -12 from 144.
\frac{10x}{10}=\frac{156}{10}
Divide both sides by 10.
x=\frac{156}{10}
Dividing by 10 undoes the multiplication by 10.
x=\frac{78}{5}
Reduce the fraction \frac{156}{10} to lowest terms by extracting and canceling out 2.
