2x – y – z = 6
5x + y + z = 1

Answer 1

Answers:
(1, 6, 1)

(-1, -2, 6)

(1, 2, -6)

(2, 1, -4)

Answer 2

I meant to ask you for help on this one too

Answer 3

This is basically another question that's exactly the same format as the one I solved before. Please look at what I did in the previous question to answer this one yourself.

Answer 4

Start by getting two equations with two variables. To do that, choose a variable to eliminate. HINT: Choose z, because you don't need to multiply to get rid of it in all three equations.

Answer 5

ok

Answer 6

then what is the next step?

Answer 7

Show me your two equations that have only two variables in both equations first.

Answer 8

2x - y -z = 6
+5x = y + z= 1

Answer 9

*+

Answer 10

Do those two equations have two variables or three? Didn't I tell you to get two equations that have only TWO VARIBALES?

Answer 11

VARIABLES*

Answer 12

Example?

Answer 13

When someone like #iforget asks you if you understand how to solve the previous question, you answer honestly. If you don't understand then please say no and not just yes and go to the next question. If you were to do a written exam, teachers don't mark your test to see whether you get the correct answer or not. Multiple choice is practice for you to know how to get the answer. Not just randomly guess at the answer.

Answer 14

And an example was shown to you in the previous question...

Answer 15

If you read what I did in the previous question, you would know an example that had two variables.

Answer 16

I meant to save it but I closed the question

Answer 17

Then go to the closed section and read what I wrote.

Answer 18

Ok I see

Answer 19

There's two sections: Open Questions and Closed Questions.

Answer 20

Yea I barely use this. I got it thanks

Answer 21

No worries.
