Answer 2

huh

Answer 3

matrix

Answer 4

that's your coefficient matrix

Answer 5

what do i multipy by for the matrix -3 ?

Answer 6

it is hard to explain witout visualization.

Answer 7

x=7/9 ... y=21/18 ... z=1/18

Answer 8

i dont know how to write matrices on this ... but that is the result of matrix reduction ... i hope ... coulda made a mistake tho :S

Answer 9

yes they work ... if only i could write up matrices i could show u the working

Answer 10

do u want working out?
