Question

How do you complete each ordered pair (4, _) so that it is a solution to 6x - y = 7?

Answer 1

`(4,color(blue)(17))`

Explanation:

Let the missing value be `k`
so that `(4,k)` is a solution to the equation
`color(white)("XXX")6x-y=7`

Substituting `(4,k)` for `(x,y)` (i.e. `4` for `x` and `k` for `y`)
we get
`color(white)("XXX")6*(4)-k=7`

`color(white)("XXX")24-y=7`

`color(white)("XXX") y=17`
