Question #59294

Answer 1

`4x-3y=18`

Explanation:

You have been given you the values for `x`, `y` and `z`.

The value of `z` is useless here, as the expression only includes `x` and `y`.

We know that:
`x=3` and `y=-2`

So, subbing these values into `4x-3y`, we get:
`4(3)-3(-2)`
`=12-(-6)`
`=12+6`
`=18`

So, `4x-3y=18`.
