Solve the linear system by the Gauss-Jordan elimination method: -2x - 3y + 2z = -2 x + y = 3 -x-3y + 5z = 8 1. 3. x + 2y = 1 - 2x - 4y = 6 2. Set up a system of equations that could be used to solve the following: "A one-pound mixture of nuts contains cashews (60 per ounce), almonds (40¢ per ounce), and walnuts (70¢ per ounce) and costs $8.90. The mixture contains the same weight of cashews as walnuts. How many ounces of each type of nut does the mixture contain?"
