Question

Need help with matrix (check attached picture)

Answer 1

Take the blue pill. Actually, I kid. I'm sure someone else can provide a useful answer. Please explain it, as I'm about to teach myself linear algebra. :P

Answer 2

thank you for the help all... been a while

Answer 3

assuming its by convention x y = n

Answer 4

x+3y = -3

y = 5

Answer 5

Aww... i could have solved that one too. Haha.

Answer 6

no assumption needed, if you read the whole thing that is ;)

Answer 7

Also, if the homework site says you're wrong, put in 1x instead x. And 1y instead of y. But only if it says you're wrong, since 1x isn't the 'normal' way of writing it.

Answer 8

thank you both... this helps me relearn for sure
