how far did you get? were you able to set up the matrix?

i was not i was so confused on this like i dont know where to start

well you first pull out the coefficients of each equation. Do you see what they are?

i do not sorry

they are simply the numbers in front of the variables

example: `4x` has the coefficient of `4`

the `-y` is really `-1y`

so four and five right

along the first equation, what are the 3 coefficients?

4 5 and 1x right

read across the row

not column

do you see what I mean?

ohh ok i got you hold on

so 4 and three for the first one right

don't forget about the -1

the first equation is really `4x - 1y + 3z = 12`

ohh yeah sorry lol

so the seciond one is 1x+4y+6z=12

-32 on the right side, not 12

opps my bad i looked at it wrong haha i acciedently looked up at the end sorry

5x+3y+9z=20 for the last

agreed? or no?

yes i agree

yeah

makes since now
