-2x+3=16
Square both sides of the equation.
-2x+3-3=16-3
Subtract 3 from both sides of the equation.
-2x=16-3
Subtracting 3 from itself leaves 0.
-2x=13
Subtract 3 from 16.
\frac{-2x}{-2}=\frac{13}{-2}
Divide both sides by -2.
x=\frac{13}{-2}
Dividing by -2 undoes the multiplication by -2.
x=-\frac{13}{2}
Divide 13 by -2.
