I haven't done any, I was coming to look for help before I did anything, I don't wanna screw it up.

you have to "screw it up" in order to learn it better

Awww, work darn. I don't have any. I know the answer to the X and Y is (1,4)

None have "1,4" its all 3 1 0 5

amistre64Best ResponseYou've already chosen the best response.3
assuming youve got the correct 1,4 solution, the augment will have to work out as x+y=5 3x+y=1 1 1 5 1 0 1 3 1 1 to 0 1 4

that is the start of the augment, yes

Well, you have three mods on the case, you can't possibly go wrong now :D

Well I am not really good in matrix, nor algebra. So I need all the help I can get.

that is the matrix to augment, but is not the augmented matrix yet

amistre64Best ResponseYou've already chosen the best response.3
because they are important

there are 3 basic methods to solving systems of equations: substitution elimination matrix row operations matrix row operations are really just a combination of the other 2

I was thinking Substitution since I know it better
 11 months ago

amistre64Best ResponseYou've already chosen the best response.3
substitution is not ideal for most situations ... its only effective on the hand picked easy peasy things they give you to practice on

terenzreignzBest ResponseYou've already chosen the best response.0
I figure if you can do elimination, Matrix Row Operations shouldn't be a problem, it's essentially the same thing, without the variables...

amistre64Best ResponseYou've already chosen the best response.3
most solutions to real world problems require a computer to work on them, and the row operations are better suited to optimize a computers functionality

Ok can we explain to the imbecile (me) how to do so?
 11 months ago

amistre64Best ResponseYou've already chosen the best response.3
row operations are pretty much the elimination method x + y = 5 : *3 3x  y = 1 3x 3y = 15 3x  y = 1  0x 4y = 16 x + y = 5 0x 4y = 16 : /4 x + y = 5 0x + y = 4 : * 1 x + y = 5 0x  y = 4  x + 0y = 1 x+0y = 1 0x + y = 4
