What is the value of x in the solution to the following system of equations? (5 points) x − y = −3 x + 3y = 5

OpenStudy (kpop4life123):

@Luigi0210

OpenStudy (redphantom9):

x + 3y = 5

OpenStudy (caozeyuan):

\[\left[\begin{matrix}1 & -1 & -3 \\ 1 & 3 &5 \end{matrix}\right]\]

OpenStudy (caozeyuan):

\[\left[\begin{matrix}1 & -1 &-3 \\ 0 & 4&8\end{matrix}\right]\]

OpenStudy (redphantom9):

did i get it right? @Kpop4life123

OpenStudy (caozeyuan):

\[\left[\begin{matrix}1 & -1&-3 \\ 0 & 1&2\end{matrix}\right]\]

OpenStudy (kpop4life123):

i cant put it in because i only have 1 try

OpenStudy (caozeyuan):

now from the second row we have y=2

OpenStudy (redphantom9):

oh ok

OpenStudy (caozeyuan):

so x+2=-3

OpenStudy (caozeyuan):

x=-5 @Kpop4life123

OpenStudy (redphantom9):

N/A

OpenStudy (kpop4life123):

wait so its both of them or only x=-5

OpenStudy (caozeyuan):

sorry

OpenStudy (caozeyuan):

x-2=-3

OpenStudy (caozeyuan):

x=-1

OpenStudy (caozeyuan):

my brain thought - is + for some reason

OpenStudy (kpop4life123):

both?

OpenStudy (caozeyuan):

not sure what you are asking for but you have a value for x which is -1, a value for y which is 2, does this answer your questions

OpenStudy (kpop4life123):

oh ok thanks and yes i was looking for the value of x
