Question #0d9c1

Answer 1

The answer is `x=y=3.`

Explanation:

This is how we solve this question using elimination method:-

`x+7y=+24 ...(i)`
`x-9y=-24...(ii)`

equation (i)- equation (ii) gives
`color(white)(......)16y=48`
`color(white)(..)=>y=3`

Putting `y=3` into (i) we get
`x+21=24`
`=>x=3`

Therefore, `x=y=3`.
