-------------
Let number of 37 cent stamps be "x"; value of those is 37x cents
The number of 20 cent stamps is "20-x" ;
value of those is 20(20-x)=400-20x cents
-----------
EQUATION:
value + value = 706 cents
37x + 400-20x = 706
17x = 306
x= 18 (This is number of 37 cent stamps)
20-x = 2 (This is number of 20 cent stamps)
