Question 398258
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.
