Question 1089386: Solve the problem by using the Gauss-Jordan method to solve a system of equations.
MIXING SOLUTIONS:
A 5% solution of a drug is to be mixed with some 15% solution and some 10% solution to get 20 mL of 8% solution. The amount of 5% solution used must be 2 mL more than the sum of the other two solutions. How many milliliters of each solution should be used?
