    First of all you convert the time into minutes like
   9*60 = 540 minutes
   12*60 = 720 minutes
   Suppose x is the number of minutes before noon then,
   T = 720-x.
   44 minute ago is t-44
   3 times past 9am is t-44 is equal to 540+ 3x
   t = 584 + 3x
   now you can solve it like
   t= 584+3x………..i
   t=720+3x……………2
   taken first equation
   t=584+3x
   put the value of t in equation
   720-x=584+3x
   4x= 136
   X=34

   Change all hours into minutes past midnight, so 9am = 540 and noon = 720.

   Let suppose x be the number of minutes before noon it is now,
   so present time t is = 720 - x.

   44 minutes ago (t-44) it was 3x past 9am: t-44 = 540 + 3x.

   No you have simultaneous equations to solve:
   t = 720 - x
   t = 584 + 3x

   cancel out t's:
   720 - x = 584 + 3x
   136 = 4x
   x = 34

   Now it is 34 minutes before 12 noon.

    difference between 9 am and 12 noon= 180 min
   let x min ago was the time when 44 minutes ago it was three times as many minutes past 9 a.m.
   so 44 min ago when time was x min to 12 noon time was 3x min past 9am
   so total min in time interval 9 to 12 are 3x + 44 + x = 4x + 44
   hence 4x + 44 = 180
   or 4x=136
   so x=34 min
   so time was 34 min before 12 noon, i.e., 11:26 when 44 min ago it was 3 times as min as many min past 9 am

   I think it might be 44. I am not sure about it.
