Solve each equation and check for extraneous solutions.     Case 1:                                    Case 2:

                                        12. | -4x | = 32

13. | x - 3 | = 9

14. 2| 3x - 2 | = 14

15. | 2u - 4 | = 12

 16. If y = 4 when x = -2, find x when y = 6. 

 17. If y = 6 when x = 2, find x when y = 12

 18. If y = 25 when x = 15, find x when y = 6

GRAPH

Find the slope and y-intercept of each line and then graph the equation.

19. 5x + y = 4

20. 9x - 2y = 10
