A person is ordered by a doctor to take 10 units of vitamin A, 9 units of vitamin D and 19 units of vitamin E each day. The person can choose from three brands of vitamin pills. Brand X contains 2 units of vitamin A, 3 units of vitamin D and 5 units of vitamin E. Brand Y has 1, 3 and 4 units respectively and Brand Z has 1 unit of vitamin A, none of vitamin D and 1 of vitamin E. (iii) Use elementary row operations to convert the matrix to reduced row echelon form. (iv) Determine the solution to the system of equations.
