Answer 2

1 0 -2 I 3 means what?

Answer 3

yes but how does it translate back to an equation

Answer 4

with x y and z in it

Answer 5

x -2z = 3

Answer 6

good, how about the second row

Answer 7

is that what i write down in the boxes below??

Answer 8

for the first row and second row boxes yes

Answer 9

the last one is the solution of the system

Answer 10

thank you!

Answer 11

i figured it out from here :)

Answer 12

ok great, the solution is pretty much there (just need to use the correct free variable and get it in the right form that the computer likes)
