Could you explain the steps, I keep getting stuck and getting decimals.

 

1.

3x-y+4z=15

2x+y-z=-8

x+5y-2z=-19

 

2. 

r+2s-4t=-15

-6r+s+2t=-24

2r-s-3t=0

 

3. 

4x-3y-6z=-24

6x+5y-6z=14

-4x+6y-4z=-4

 

4.

-5a-2b+3c=-16

-a-b-c=5

-2a+2b-5c=10

 

5.

-x+y-z=-3

3x-2y-4z=22

-3x+y+3z=-19

 

6.

-x+y-4z=12

2x-5y+3z=-17

-6x-2y+4z=8
