\sqrt{\frac{47}{2}-\frac{3}{2}x}=4
Divide each term of 47-3x by 2 to get \frac{47}{2}-\frac{3}{2}x.
-\frac{3}{2}x+\frac{47}{2}=16
Square both sides of the equation.
-\frac{3}{2}x+\frac{47}{2}-\frac{47}{2}=16-\frac{47}{2}
Subtract \frac{47}{2} from both sides of the equation.
-\frac{3}{2}x=16-\frac{47}{2}
Subtracting \frac{47}{2} from itself leaves 0.
-\frac{3}{2}x=-\frac{15}{2}
Subtract \frac{47}{2} from 16.
\frac{-\frac{3}{2}x}{-\frac{3}{2}}=-\frac{\frac{15}{2}}{-\frac{3}{2}}
Divide both sides of the equation by -\frac{3}{2}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=-\frac{\frac{15}{2}}{-\frac{3}{2}}
Dividing by -\frac{3}{2} undoes the multiplication by -\frac{3}{2}.
x=5
Divide -\frac{15}{2} by -\frac{3}{2} by multiplying -\frac{15}{2} by the reciprocal of -\frac{3}{2}.
