Question

Solve the linear system. 5x+6y=-9
-x-8y=-5

Answer 1

multiply the second equation by \(5\) then add them up in a column

Answer 2

On both sides?

Answer 3

yes of course
multiply every part of the second equation by 5
the \(-x\) the \(-8y\) and also the \(-5\)

Answer 4

Okay I got y=1. Is that it?

Answer 5

idk i didn't do it

Answer 6

Well do you not need to solve for x in a linear system?

Answer 7

yes it is \(y=1\) right

Answer 8

you know \(y=1\) so you certainly know what \(x\) is because \( 5x+6y=-9\) and since \(y=1\) this says
\[5x+6\times 1=-9\\
5x+6=-9\] etc

Answer 9

Oh I see. Thanks . . once again. xD
