I need help with this one question; can someone please help?

Give any three ordered pairs that are solutions of the equation:

2x - 3y= 12

I already have one (9,2)

Thanks!

    pick any even number for y,
    say y = 4
    then 2x-12 = 12
    2x = 24
    x = 12 -----> (12,4)

    try another one.
    You can check if your point is correct by subbing it back in

    You posted this same type question earlier and were given a response by Rick P that said your two answers were correct and explained what you needed to do to make as many ordered pairs as needed. Just use that same procedure for this one. If you post your solutions someone will be glad to check them.

    OK, Thanks to both of you.
    I will be sure to post when I get the solution
