-x+7=1
Square both sides of the equation.
-x+7-7=1-7
Subtract 7 from both sides of the equation.
-x=1-7
Subtracting 7 from itself leaves 0.
-x=-6
Subtract 7 from 1.
\frac{-x}{-1}=-\frac{6}{-1}
Divide both sides by -1.
x=-\frac{6}{-1}
Dividing by -1 undoes the multiplication by -1.
x=6
Divide -6 by -1.
