you get a life! don't you see that you annoy half of the population inside this forum? yet you stay to prove a point. to prove that you simply don't care, and that comes off as obnoxious, and kong. the thread title just proves us that you need affection from internet buddies, just get out!

It's a highschool level problem dude. http://en.wikipedia.org/wiki/Gaussian_elimination

gaussian elimination makes that shit so much easier.

Maybe you're doing row operations on the matrix but not on applying them on the right hand side?

add the first two equations and get rid of a variable

400x + 300y + 300z = 5000
200x + 160y + 120z = 2400


400x + 300y + 300z = 5000
-400x - 320y - 240z = -4800

ad0d two equations and solve for one of the variables (y, or z) then substitute

I've finished linear algebra few days ago and have absolutely no intention of solving those problems again.

Oh, and my username is perfect for this thread.

that's way way below the

group.

But eh, America. When I graduated in California, all that was required (in mathematics) was a passing grade in GEOMETRY. Take into account, the last mathematics class in middle school is Pre-Algebra, which is the pre-requisite for Geometry.

Are you required to learn Matrices? Both times I've come across the method in my life, the instructor's have passed it on saying it's some archaic compton shit. The substitution from above(shadow_419) is what I was taught and it's very easy.
