Question

How do you complete each ordered pair (13, _) so that it is a solution to 6x - y = 7?

Answer 1

For each ordered pair, substitute in what you know (so either the x or y value) and solve for the other to get `(13,71)`

Explanation:

For each ordered pair, substitute in what you know (so either the x or y value) and solve for the other within the equation. For example, in your question with (13,_), `x=13` so let's substitute that into the equation:

`6x-y=7`

`6*13-y=7`

`78-y=7`

And now add y and subtract 7 to both sides to get

`y=71`

So the ordered pair is `(13,71)`
