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)
