Question

is there an easy way to solve system of linear equation without using the matrix?

Answer 1

-x-2y+4z=13
2x+y+7z=13
-7x-8y-2z=-7

Answer 2

It's easier to use matrix. You can note right away if there is a solution to the system or if it has multiple solutions or a unique one.

Answer 3

i have trouble solving the matrix

Answer 4

Can you set up the system as a matrix?

Answer 5

yes,

Answer 6

What level of math are you in?

Answer 7

i'm taking calc 1

Answer 8

Sorry never learned how to solve systems using matrices until I started linear algebra so I don't know how to do it in a way that you will understand.

Answer 9

ok thank u

Answer 10

i do understand it but i get confused.

Answer 11

There are three row operations you can do. You can add rows together and you can add scalar multiples and you can scale rows.

Answer 12

You do that in order to get the matrix into echelon form and then into reduced echolon form

Answer 13

ok. thanks :)
