Does your graphing utility have a feature that allows you to solve linear systems by entering coefficients and constant terms? If so, use this feature to verify the solutions to any five exercises that you worked by hand from Exercises 5–16.

Data from exercise 5-16

5. The solution set is {(2, 3, 3)}.

6. The solution set is {(1, –1, 1)}.

7. The solution set is {(2,−1,1)}.

8. The solution set is {(1, –1, 2)}.

9. The solution set is {(1, 2, 3)}.
