Question

Determine if you have to add or subtract. Then find out y's value and then x's value.

2x+3y=23
-2x+y=13​

Answer 1

you add and the value of y is in the attachment

Explanation:

Answer 2

Add

`x=-2`

`y=9`

Explanation:

To find the value of
`y`, we can add the two equations:

`2x+3y+(-2x+y)=23+13`

`2x+3y-2x+y=36`

`4y=36`

`y=9`

To find for
`x`, we can use substitution:

`2x+3y=23`

`2x+3(9)=23`

`2x=-4`

`x=-2`

∴
`x=-2,y=9`

Hope this helps :)
