solve using substitution. x-4y=-13 -x-4y=13

makaylab:

plz help.

NoodlesAndRiceYT:

are the 2 equations suppose to be together?

makaylab:

ye

NoodlesAndRiceYT:

oh its closed now

NoodlesAndRiceYT:

So, they are together and you need to subtract them both together?

makaylab:

sub

NoodlesAndRiceYT:

Ok so then how do think we do this?

makaylab:

4y and 4y cancel out

NoodlesAndRiceYT:

that is incorrect

NoodlesAndRiceYT:

look closely

makaylab:

x?

NoodlesAndRiceYT:

wait im trying to figure this out now im confused- so the 4y are both negatives, wouldnt that mean they dont cancel out?

makaylab:

\[x+4y=-13 \] \[-x-4y=13\]

NoodlesAndRiceYT:

are you sure thats the equation? it says different at the top.

makaylab:

yes i mis read it

NoodlesAndRiceYT:

now you are saying two different things and it is more confusing me when i just thought i knew how to solve it you send me something else that makes the whole thing different and even more confusing.

NoodlesAndRiceYT:

i think i got this.

makaylab:

ok

makaylab:

plz hurry

makaylab:

show all work too

NoodlesAndRiceYT:

if you have to solve using subtiusion, what would the 4y be then if you do what the question wants?
