Re: Beat I am mathematically challenged today
holy crap, I made a mistake and it's all messed up. I hate life.

Re: Beat I am mathematically challenged today
sorry, forgot to say, that one condition is that none of the variables can be negative

edit: thanks for this thread. now i'm def going back to school [/ QUOTE ] seriously. i am doing something and one small part involves system of equations. and i'm like "oh [censored], how do i do this stuff again" |
Re: Beat I am mathematically challenged today
"none of the variables can be negative"
Does that mean X > 0 or the coefficient > 0? |

2 equations, 4 unknowns. do i just substitute? when doing so things get really cumbersome. $25 transfer on stars (when i get home tonight) if someone wants to tackle it (probably easy to you geeks). first person gets $$. 6w + 6x + 4y + 2z = 5 w + x + y + z = 1 [/ QUOTE ] w = 0.25 x = 0.25 y = 0.5 z = 0 6(.25) + 6(.25) + 4(.5) + 0 = 5 1.5 + 1.5 + 2 = 5 0.25 + 0.25 + 0.5 + 0 = 1 If you throw in that 3rd equation..this doesn't work |
Re: Beat I am mathematically challenged today
y = 0.5 -2z
x = 0.5 + -1y you need 1 more equation |
Re: Beat I am mathematically challenged today
w=.25, x=.5, y=0, z=.25
I win. |

w=.25, x=.5, y=0, z=.25 I win. [/ QUOTE ] Damn. Just beat me. Matrices FTW |
Re: Beat I am mathematically challenged today
Yep.
