## anonymous one year ago Linear equation A= x + y + z/3 solve for y

1. anonymous

I got the answer y = 3A-x-z but only cause i followed an example so im kind of confused.

2. anonymous

same here

first move all varibales to one side, leaving y alone

5. anonymous

On the answer sheet it said it was lol but my teacher said it could be more than one answer

Wait up, is it $A= \frac{x+y+z}{3}$ or $A= x+ y + \frac{z}{3}$

8. anonymous

the first one

first multiply both sides by 3 to get $3A = x+y+z$

11. anonymous

then subtract x and z $3A-x-z=y$

12. anonymous

Thats the part i get confused where am i subtracting x and z?

13. anonymous

y=$\frac{ a-z-x }{ 3 }$

14. anonymous

15. anonymous

from here: $3A = x+y+z$ you subtract x and z

16. anonymous

no you divide by three to get y alone

17. anonymous

ohhh i see because youre trying to get the y alone

18. anonymous

yah

19. anonymous

and what ever is on the other side is y

20. anonymous

okay thank you both :)

no problem
