Question: Solve the indicated or given systems of equations by an appropriate algebraic method. A 6.0% solution and a 15.0% solution of a drug are added

Solve the indicated or given systems of equations by an appropriate algebraic method.

A 6.0% solution and a 15.0% solution of a drug are added to 200 mL of a 20.0% solution to make 1200 mL of a 12.0% solution for a proper dosage. The equations relating the number of milliliters of the added solutions are

x + y + 200 1200 0.060x+0.150y + 0.200(200) = 0.120(1200) =

Find x and y (to three significant digits).

x + y + 200 1200 0.060x+0.150y + 0.200(200) = 0.120(1200) =
