Best ResponseYou've already chosen the best response.0well u take the first row.and u divide by 2.then it changes from 2 4 3 6 to 1 2 3/2  3

anonymous

Best ResponseYou've already chosen the best response.0ohh! u divid by two not thr 2nd row :/lol now i got that ok

anonymous

Best ResponseYou've already chosen the best response.0then your rows are now like this 1 2 3/2  3 3 5 6  3 0 1 1  2

Best ResponseYou've already chosen the best response.0sorry. multipy row 1 by 3 the subtract it from row 2 the u have a reduced row 2

Best ResponseYou've already chosen the best response.01 2 3/2  3 _ _ _  _ 0 1 1  2 the only r0w that changes is row 2

anonymous

Best ResponseYou've already chosen the best response.0yea,ok i get that so row to is now 3 8 9/2 3

anonymous

Best ResponseYou've already chosen the best response.03(3X3) = 0 That is how u do it.

anonymous

Best ResponseYou've already chosen the best response.0meaning u take 1 from row1 and multiply by 3 the u subtract the answer from 3 in row 2 and u get ur as 0. do the same with the second term

anonymous

Best ResponseYou've already chosen the best response.0then u get 1 2 3/2  3 0 1 3/2  6 0 1 1  2

anonymous

Best ResponseYou've already chosen the best response.01 2 3/2  3 0 1 3/2  6 0 1 1 2 in row 1 u must eliminate 2 and in row 3 must eliminate 1.

Best ResponseYou've already chosen the best response.0add row 3 and row 2 to get 1 2 3/2 3 0 1 3/2 6 0 0 1/2 4 and u jst eliminated 1 from row 3

anonymous

Best ResponseYou've already chosen the best response.0then u get 1 0 9/2 9 0 1 3/2  6 0 0 1/2 4

anonymous

Best ResponseYou've already chosen the best response.0what is 4 divided by half

anonymous

Best ResponseYou've already chosen the best response.0then u have 1 0 9/2  9 0 1 3/2  6 0 0 1  8 what do u think u should do to eliminate 9/2?

anonymous

Best ResponseYou've already chosen the best response.0what do u get for row1?

anonymous

Best ResponseYou've already chosen the best response.0now u got 1 0 0  27 0 1 3/2 6 0 0 1 8

anonymous

Best ResponseYou've already chosen the best response.0u must now eliminate 3/2.how do u think u do that?

anonymous

Best ResponseYou've already chosen the best response.0how do you think u can do it?

anonymous

Best ResponseYou've already chosen the best response.0sure.which row can u use to eliminate it?

anonymous

Best ResponseYou've already chosen the best response.0good.how do u do that?

anonymous

Best ResponseYou've already chosen the best response.0multiply row3 by 3/2 and add it to row2

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0that way 1 becomes 3/2 and you can add that to row 2.the 3/2 + 3/2 = 0 which eliminates 3/2

anonymous

Best ResponseYou've already chosen the best response.0then u have 1 0 0 27 0 1 0 6 0 0 1 8 what is ur x,y and z?
