I know that I have to form at least two equations from this problem because I have to use the substitution or elimination method to solve this problem. I know that the answers are: D1=5 and D2=4 but I don't know what equations to form and what to substitute or eliminate

**drwls**, Thursday, July 24, 2008 at 2:45pmLet G be the number of "Units" of D1 and H be the number of un its of D2.

The equations you have to satisfy are:

G + 2H = 13(the amount of drug X needed)

2G + 3H = 22 (the amount of drug Y needed).

2G + 4H = 26

H = 4

G = 13 - 8 = 5
