OpenStudy (anonymous):

Give me a moment, I'll see if I can answer any of these.

OpenStudy (usukidoll):

so much vertices X>X

OpenStudy (anonymous):

Omg my little pony fan!

OpenStudy (usukidoll):

ah I can do the other two... you can either use elimination method or subistution...dang I'm so spoiled with the matrix version.

OpenStudy (usukidoll):

yeah but I'm a lady in real life, technically I'm a pegasister.

OpenStudy (anonymous):

Lol, thats fine man! I to am a pegasister

OpenStudy (usukidoll):

anyway while I try to recover from the farting preacher jokes... you need to solve for one of the variables like try to solve for x and then y and finally z .... then plug the values back in, but since I learned the matrices method ...it's way faster.

OpenStudy (usukidoll):

it's a 3 x 3 square matrix... augmented alb

OpenStudy (usukidoll):

ughhh we gotta do by elimination ok... add equation 1 and equation 3 http://assets.openstudy.com/updates/attachments/5259cbc0e4b0ede9e448a511-jamielovesmickey-1381616628540-z.png

OpenStudy (usukidoll):

and add equation 2 and equation 3... label the results with new numbers or you'll feel lost fast

OpenStudy (usukidoll):

and after you do that...either eliminate the y or the z from the new equations and solve for y or z and then plug it back in..

OpenStudy (usukidoll):

wait I'm trying to finish my homework...after I'm done then I can draw it out

OpenStudy (usukidoll):

but I'm so spoiled by the matrix version I'm like wahhhhhh I don't wanna go back!!!

OpenStudy (usukidoll):

OpenStudy (usukidoll):

honestly that was more time consuming than matrix style. you should learn that instead.

OpenStudy (usukidoll):

one you master it it's easier and fun, but knowing our educational system, matrices are reserved for "university" yeah right....anyone can do it

OpenStudy (usukidoll):

ya

OpenStudy (anonymous):

I was correct, I'm glad.
