I got this:

z=(a²fl-abel-adfi+bdei+abhi-bdei-a²hj+adej)/(abgi-acfi+acej-a²gj+a²fk-abek)

Just looking at all this Math is making me physically angry
;-;;;;;;;;;;;;;;;;;;;;;

 

[Pikmon2]

too many numbers not enough action

Z- out of 10

You have the same answer as me only you solved for x[1] with x[2] and x[1] with x[3] to get your answer, I did it with x[1] and [2] and x[2] = x[3]. By the way, you can still cancel out bcei.

Actually, I worked with y first.

I was thinking maybe I could rework it using Cramer's rule with matrices. But I don't think that would make it any simpler either is the thing :L

HOW ARE YOU ALL SO GOOD AT MATH THIS IS SO UNFAIR.

You're only 11, it could explain
They are at least 15 year old or older.

Oh~

EDIT: Damn, I'll never be able to understand them now.

I'm 13 and a half

Well, someday you'll learn higher mathematics

You sure about that? ._.

I've always sucked at Maths, truth be told... *weakest subject is Maths*

Well, you'll get it sooner or later. It's just simple substitution

(Granted, my birthday's coming up, and soon I'll be 12, but...)

 

[Swate]

Bah. With the right education, possible 1 on 1 tutoring or something, you'd pass algebraic things with flying colours.

 

[zezmi]

Yay math!
Math and Blocktopia, sounds like endless fun~

What I did:

x = (d - by - cz)/a
x = (h - fy - gz)/e
x = (l - kz - jy)/i

(d-by-cz)/a = (h-fy-gz)/e
ah - fay - agz = ed - bey - ecz
bey - fay = ed - ecz - ah + agz
y = (ed - ecz - ah + agz)/(be - fa)

(h - fy - gz)/e = (l - kz - jy)/i -->
y = (el - kez - ih + giz)/(je - fi)

(ed - ecz - ah + agz)/(be - fa) = (el - kez - ih + giz)/(je - fi) -->
z(jce² + gibe + kefa - bke² - jeag - fiec) = jde² - jeah - fied + fiag - ble² + beih + feal - faih
z = (jde² - jeah - fied + fiag - ble² + beih + feal - faih)/(jce² + gibe + kefa - bke² - jeag - fiec)

Though, I have no idea if either one of ours is correct because it's an absolute chaos with all those variables. (Maybe they're the same just written differently)

What kind of sorcery is this. I... my.. my brain...why...I don't even..my brain just melted.

gg guys, gg
i have to try this

Nevermind the answer - what's this used for?

Well, it's to find a formula to solve simultaneous equations with 3 unknowns.
