-\frac{2}{3}\sqrt{-x+1}+7-7=3-7
Subtract 7 from both sides of the equation.
-\frac{2}{3}\sqrt{-x+1}=3-7
Subtracting 7 from itself leaves 0.
-\frac{2}{3}\sqrt{-x+1}=-4
Subtract 7 from 3.
\frac{-\frac{2}{3}\sqrt{-x+1}}{-\frac{2}{3}}=-\frac{4}{-\frac{2}{3}}
Divide both sides of the equation by -\frac{2}{3}, which is the same as multiplying both sides by the reciprocal of the fraction.
\sqrt{-x+1}=-\frac{4}{-\frac{2}{3}}
Dividing by -\frac{2}{3} undoes the multiplication by -\frac{2}{3}.
\sqrt{-x+1}=6
Divide -4 by -\frac{2}{3} by multiplying -4 by the reciprocal of -\frac{2}{3}.
-x+1=36
Square both sides of the equation.
-x+1-1=36-1
Subtract 1 from both sides of the equation.
-x=36-1
Subtracting 1 from itself leaves 0.
-x=35
Subtract 1 from 36.
\frac{-x}{-1}=\frac{35}{-1}
Divide both sides by -1.
x=\frac{35}{-1}
Dividing by -1 undoes the multiplication by -1.
x=-35
Divide 35 by -1.
