## monroe17 2 years ago Solve the equation. 2x-3y-5z=-16

1. Zelda

Impossible. You need a minimum of 3 equations, or two given variables.

2. monroe17

there's more.. I need to find the n-vector form

3. monroe17

x __ __ __ y = __ + __ s + __ t z __ __ __

@saifoo.khan can you help me please?

5. JEdwards85

2x-3y-5z=-16 x+3y+5z-16/2=1 1/2y+2 1/2z-8 that what my calculator said.

6. monroe17

^ huh?

7. JEdwards85

I put it to my algebra calculator and that the answer I got.

8. monroe17

I'm pretty sure that's wrong ^. But thanks for trying.

9. JEdwards85

Ok

10. mathsmind

11. mathsmind

and if not can you kindly tell me are you solving for x

12. monroe17

nope, someone tried. I can't figure it out to save my life. In my second comment ( up there ) I'm solving for all the "__"

13. mathsmind

ok it is simple

14. mathsmind

first of all solve for x then for y then for z

15. mathsmind

i will show you how

16. monroe17

you can't solve for x,y,z unless you have more equations..

17. mathsmind

wait and you will see

18. mathsmind

2x-3y-5z=-16

19. mathsmind

step one: 2x = 3y + 5z =16

20. mathsmind

step two: $x = \frac{ 3 }{ 2 }y + \frac{ 5 }{2 }z -8$

21. mathsmind

$x = 1.5y + 2.5z -8$

22. mathsmind

are you following

23. monroe17

yes

24. mathsmind

so this is your value of x

25. mathsmind

now i will solve for y if you want?

26. mathsmind

are you there?
