## Rayyee 2 years ago Would there be no solutions? -x+2z=-9 -x-3y-4z=2 -3x-2y+2z=17

1. hba

@Rayyee Did you try to solve it ?

2. hba

How can you say that there will be no solutions ?

3. Rayyee

Because when I plugged it in the Calculator ( you know the Matrix method) it said like error meaning there is no solution?

4. hba

Well there will be solutions,What about trying the substitution method ?

5. hba

@Rayyee Or Is your question related to Matrices ?

6. Rayyee

OKay no I tryed doing that so I got -21-42z=77 and 21y+42z=33 it would cancel each other out...

7. hba

yeah adding them up will get you y :)

8. Rayyee

oops I ment -21y-42z=77 and 21y+42z=33

9. Rayyee

the y val and z value cancels O:

10. hba

Well then there is no solution.

11. hba

@Rayyee I think you are done ?

12. Rayyee

ut may you double check X) Because maybe I made a mistake but to me I keep re checking and it seem slike I am still right

13. hba
