these are the last problems I need please :)

SECTION 2.3 PROBLEM SET: SYSTEMS OF LINEAR EQUATIONS - SPECIAL CASES Solve the following inconsistent or dependent systems by using the Gauss-Jordan method.

1) 2x + 6y = 8

x + 3y = 4

3) 2x - y = 10

- 4x + 2y = 15

4) x + y + z = 6

3x + 2y + z = 14

4x + 3y + 2z = 20

5) x + 2y - 4z = 1

2x - 3y + 8z = 9

8) x + y + 2z = 0

x + 2y + z = 0

2x + 3y + 3z = 0
