Question

I need help with system B. I have one right. And if the answer is infinitely. It asks to satisfy and it has Y=

Answer 1

We have the next system of equations

`\begin{gathered} -5x-y=5 \\ -5x+y=5 \end{gathered}`

We can sum both equations we can eliminate one variable

`\begin{gathered} -10x=10 \\ \end{gathered}`

then we isolate the x

`x=(10)/(-10)=-1`

Therefore x=-1 then we substitute the value of x in order to find the value of y in the second equation

`-5(-1)+y=5`

Then we simplify

`5+y=5`

Then we isolate the y

`y=5-5`
`y=0`

ANSWER

x=-1

y=0
