I really need the answer thanks :)

Answer 1

are you in linear algebra class?

Answer 2

@glares25

Answer 3

yup :)

Answer 4

so do you have the augmented matrix set up yet?

Answer 5

not yet,

Answer 6

my answer is leading me to nowhere

Answer 7

so we have <10, 8, -4, 16; 8, -4, 10, 42; 4, 10, 8, 42>

where ; denotes the next collum. we cool?

Answer 8

where you go @tyteen4a03 ?

Answer 9

first I would multiply the entire matrix by the scaler 1/2 to make life nice.

in other words devide ^^^ each of those numbers by 2

Answer 10

all of this 10, 8, -4, 16; 8, -4, 10, 42; 4, 10, 8, 42 divide to two ?

Answer 11

devide by 2
so we have
