    notice how 2x = 0, so that makes x = 0. if 6y = 10, then y = ???

    @SammiJS you have the right approximation for y. It's better to use a fraction because it's more exact

    okay so the answer is 0,5/3?

    I'd use parenthesis to indicate an ordered pair but I guess you can simply list the values in a comma separated list
