**tchrwill**, Wednesday, November 23, 2011 at 10:08amLetting x, y, and z equal the numbers of .02, .08 and .14 cent stamps.

1-x = 2y + 5

2-z = 3y

3-.02x + .o8y + .14z = 2.26

4-Times 100 yields 2x + 8y + 14z = 226

5-Substituting (1) and (2) into (4) yields

..2(y + 5) + 8y + 14(3y)

6-Can you take it from here?
