New question http://prntscr.com/cwpoyf

OpenStudy (3mar):

Well, I am here.

OpenStudy (mrnood):

Since this is multichoice the quickest way is to look at the last equation 3x-z =5 take the x and z values from the answers and try them. Only one is correct

OpenStudy (3mar):

@Lemanual

OpenStudy (lemanual):

Can you go step by step with me?

OpenStudy (3mar):

Can you stay with me?

OpenStudy (mrnood):

can you write the x and z values from the first answer?

OpenStudy (lemanual):

Who do I talk to I'm confused? do I talk to you Mr or Mar

OpenStudy (mrnood):

let him try

OpenStudy (3mar):

You choose in order not to be confused!

OpenStudy (lemanual):

OK so 2x+y−z=−35x−2y+2z=243x−z=5 that?

OpenStudy (lemanual):

So how do I answer this one?

OpenStudy (3mar):

me or Mr?

OpenStudy (mrnood):

Just do it @3mar

OpenStudy (3mar):

@MrNood your turn

OpenStudy (3mar):

I am busy sorry

OpenStudy (lemanual):

doesn't matter really

OpenStudy (mrnood):

Since this is multichoice the quickest way is to look at the last equation 3x-z =5 take the x and z values from the answers and try them. Only one is correct SO write the x and z values from the first answer I'll help from there

OpenStudy (lemanual):

So type the answers that are x and z from the question

OpenStudy (mrnood):

no - look at the answers - choose the x and z values from the first option and write them here:

OpenStudy (lemanual):

The answers don't have x and z in them but if you're talking about the question 2x+y−z=−3

OpenStudy (lemanual):

I'm not good with math

OpenStudy (mrnood):

The reason I asked it like that was to see if you understood that the 3 values in theanswers represent x,y and z What methods do you know for solving systems of equations?

OpenStudy (lemanual):

None I need help understanding methods

OpenStudy (mrnood):

Sorry - you need to study your text or classnotes - I cannot teach the whole topic here in an answer. We must expect some contribution from the poster in answering questions.

OpenStudy (lemanual):

wow

OpenStudy (lemanual):

But I am asking you to give me 1 method..
