Question

Thank you show your work<3
x=
y=

Answer 1

x=-5

y=6.5

Explanation:

if x=-5 then x+2y=8 could be rewriten as -5+2y=8 then you add 5 on both sides and you get 2y=13 then divide both sides by 2 and you get y=6.5

Answer 2

`x=-5,\\y=(13)/(2)`

Explanation:

`\begin{cases}x+2y=8,\\x=-5\end{cases}`

Substitute the second equation into the first (
`x=-5`):

`-5+2y=8,\\2y=13,\\y=\boxed{(13)/(2)}`

The second equation already denotes
`x=-5`. Therefore,

`\boxed{x=-5,\\y=(13)/(2)}`
