This is the problem: x + y = -4 y + z = -9 x + z = 1 This is how I tried to solve it: x + y = -4 --> y = -x - 4 y + z = -9 --> -x - 4 + z = -9 .......................-x + z = -5 .....................+ x + z = -1 .......................2z = -6 ........................z = -3 y - 3 = -9 y = -6 x - 6 = -4 x = 2 (2,-6,-3) I know this is wrong. Could somebody please show me how to do this problem, or show me where I went wrong. Please.

[QUOTE=John the Gr8;27674765]Here's the mistake. x + z = 1[/QUOTE] Thank-you so much.
Fuck, I was gonna say that. Otherwise, it looks good.
[QUOTE=Number-41;27674870] z+5+z=-1 z=-2 [/QUOTE] z=-3 --> z+5+z=-1 --> 2z=-6 --> z=-3
x=3 y=-7 z=-2
Dude this is like eighth grade shit seriously
Whoa, this is complicated, they don't teach us stuff like that in College anymore, thank god.

[QUOTE=CoolCorky;27676273]If Jenny has six apples and Johnny has one apple and they put them together what do they get? [sp]A baby.[/sp][/QUOTE] I dunno where you learnt about sex, but unless you've got some kinky fetish it usually doesn't involve apples.
