Question

What is the solution of the system of equations?

Answer 1

Do you know how to use matrices? It makes solving such a problem extremely easy.

Answer 2

nope

Answer 3

Do you have a graphing calculator?

Answer 4

no i can use online ones tho im home schooled

Answer 5

It would help though. If you plan on taking future math classes. Okay.
So it depends on how you want to solve it. I can show you how to solve it using matrices. Which is probably as easy adding.

Answer 6

You can solve it using elimination, substitution, or matrices. Matrices is normally studies later on in the course. Please let me know which one you prefer.

Answer 7

matrices

Answer 8

okay

Answer 9

Do you know what row reduction echelon form is?

Answer 10

Here, let me just give you the answers, x=4, y=-1, z=-3.
Then let me explain how to do this problem if you wish so.

Answer 11

I would prefer straight up elimination.

Answer 12

please explain cuz im lost

Answer 13

What math class are you in? I don't want to get ahead of what you have studied, which could be why matrices might seem too complicated and new for you.

Answer 14

There are three ways to solve this question:

Matricies
Substitution
Elimination

Which one have you learned?

Answer 15

none

Answer 16

beacuse the techer wass supposed taught matrices but the leesson was skipped cuz of hurrican sandy

Answer 17

so i just need someone to explain it

Answer 18

and im in algebra 2

Answer 19

Ohh. I can't explain matrices sorry :( . I hope you are okay from Hurricane Sandy btw!

Answer 20

yeah im fine can u explain substitution or elimination i can do the two variables but not the three variables
