-x+18=49
Square both sides of the equation.
-x+18-18=49-18
Subtract 18 from both sides of the equation.
-x=49-18
Subtracting 18 from itself leaves 0.
-x=31
Subtract 18 from 49.
\frac{-x}{-1}=\frac{31}{-1}
Divide both sides by -1.
x=\frac{31}{-1}
Dividing by -1 undoes the multiplication by -1.
x=-31
Divide 31 by -1.
