In Reply to: augmented matrix row reductions posted by jemma franklin on September 22, 2002 at 15:25:42:
: Hi guys. Ive been able to answer these type with less variables but these have me stumped. They are supposed to be answered using augmented matrix in row reduced echelon form. Any help would be great!!..
: x + 2x + 3x + 5x - 3x = 34
: 5x + x + 5x + 7x + x = 21
: 7x - 3x + x - 2x + 2x = 33
: x + 5x - 2x - 14x - 4x = 11
: and
: x + 2x + 3x + 5x - 3x = 34
: 5x + x + 5x + 7x + x = 21
: 7x - 3x + x - 2x + 2x = 33
: x - 6x - 7x - 14x + 4x = -20
every variable is x? you better recheck the problem. and if there happen to be subscripts, then follow the same procedure that you would if there were fewer variables. you know, the procedure you said you understood if there were fewer variables
