Please, use FORTRAN An electronics company makes transistors, resistors and computer chips. Each transistor uses four copper units, one zinc unit, and two glass units. Each resistor uses three, three, and one unit of each material, respectively, and each computer chip uses two, one, and three units of these materials, respectively. Putting this information in a table, you have: COMPONΕNT СООРER ZINC GLASS TRANSISTOR RESISTOR CHIP 1 3 1 3 1 3 The supply of these materials varies from week to week. So the company needs to set a different production target for each week. For example, in one week the total amount of materials available was 960 units of copper, 510 units of zinc, and 610 units of glass. a) Determine the equation system for this prođuction goal b) Solve the linear system using the Gauss-Seidel method to determine the number of transistors, resistors and computer chips manufactured that week. c) Confirm using the Gauss subroutine the values found by the Gauss-Seidel method
