Exercises 72-74 will help you prepare for the material covered in the next section. In each exercise, refer to the following system: { 3 x − 4 y + 4 z = 7 x − y − 2 z = 2 2 x − 3 y + 6 z = 5. a. Select a value for z other than 0 or 1 and show that ( 12 z + 1 , 10 z − 1 , z ) satisfies the system. b. Based on your work in Exercises 72-74 (a), how does this system differ from those in Exercises 21-34?
