I’m working on a Calculus exercise and need support.

An electronics company produces transistors, resistors, and computer chips. Each transistor requires 3 units of copper, 1 unit of zinc, and 2 units of glass. Each resistor requires, 3, 2, and 1 units of the three materials and each computer chip 2, 1, and 2 units of these materials, respectively. How many of each product can be made with 965 units of copper, 500 units of zinc, and 880 units of glass. Solve this exercise by using the inverse of the coefficient matrix to solve the system of equations.
