Solve the rational equation. (Enter your answers as a comma-separated list. If there is no solution, enter NO SOLUTION.)squareroot 16 - x = 4  x = NO SOLUTION   
  
  Solution
sqrt ( 16 - x) = 4
squaring both sides to get rid of the radical sign
{sqrt ( 16 - x)}^2 = 4^2
16 - x = 16
subtracting 16 from both sides
-x = 16-16
-x = 0
or
x = 0
