-3x+1=64
Square both sides of the equation.
-3x+1-1=64-1
Subtract 1 from both sides of the equation.
-3x=64-1
Subtracting 1 from itself leaves 0.
-3x=63
Subtract 1 from 64.
\frac{-3x}{-3}=\frac{63}{-3}
Divide both sides by -3.
x=\frac{63}{-3}
Dividing by -3 undoes the multiplication by -3.
x=-21
Divide 63 by -3.
