3) a. Solve the following system of linear equations by using inverse matrix method. 2 x-0 y = 9 0x + 5y = 2 b. Suppose that a company produced and sold two types of products. If they sold monthly xl items of one of the products at the rate of 592 baisa per item and x2 items of second product at the rate of 20 baisa per item. Estimate the income if they sold 32000 items of first product and 55000 items of second product in a year.
