You can  put this solution on YOUR website! Let x = # of 2-points made, and y = # of 3-points made. 
Then x  +y = 37, 
2x  +3y = 80.
 
From the top equation, y = 37 - x.  Substitute this into the bottom equation:
 
2x + 3(37 - x) = 80 
2x + 111 - 3x  =80 
-x  = - 31 
x = 31, # of 2-points made, and  
37 - x = 6, the # of 3-points made.
