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.
Dont you have a parents for this?
i learnt this really handy thing somewhere a while back.

Here's the mistake.
x + z = 1

Thank-you so much.
Fuck, I was gonna say that. Otherwise, it looks good.
Whoa, this is complicated, they don't teach us stuff like that in College anymore, thank god.

I dunno where you learnt about sex, but unless you've got some kinky fetish it usually doesn't involve apples.
You kidding me, right? :shobon:
