-x+3=16
Square both sides of the equation.
-x+3-3=16-3
Subtract 3 from both sides of the equation.
-x=16-3
Subtracting 3 from itself leaves 0.
-x=13
Subtract 3 from 16.
\frac{-x}{-1}=\frac{13}{-1}
Divide both sides by -1.
x=\frac{13}{-1}
Dividing by -1 undoes the multiplication by -1.
x=-13
Divide 13 by -1.
