Homework Help: Pre-Calculus

Posted by Andrea on Thursday, July 24, 2008 at 2:01pm.

The treatment of a certain viral disease requires a combination dose of drugs D1 and D2. Each unit of D1 contains 1 milligram of factor X and 2 milligrams of factor Y, and each unit of D2 contains 2 milligrams of factor X and 3 milligrams of factor Y. If the most effective treatment requires 13 milligrams of factor X and 22 milligrams of factor Y, how many units of D1 and D2 should be administered to the patient.

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
