The product of 9 and a number is 12 less than three times that number.


Can anyone explain what the problem is? I dont understand what its asking

Verified Answer :

\(n-the\ a\ number\\\\9n=3n-12\ \ \ \ |subtract\ 3n\ from\ both\ sides\\6n=-12\ \ \ \ \ |divide\ both\ sides\ by\ 6\\\boxed{n=-2}\)

9x = 3x - 12
 -3x  -3x       
  6x = -12
   6      6
   x = -2
