Earlier I posted a qustion about ordered pairs and I was asked to re-post the answer when I get it.

2x - 3y= 12

These are the two I had: (9,2) and (12,4)

I found this one: (15,6)


  • Pre-Algebra [FOUND THE ANSWER] -

    There an infinite number or ordered pairs satifying
    2x - 3y = 12.

    1--Divide through by the lowest coefficient, 2, yielding x - y - y/2 = 6.
    2--y/2 must be an even integer k making y = 2k
    3--Subbing back into (i) yields 2x - 6k = 12 making x = 6 + 3k
    ...and so on.

    I posted this problem earlier and you answered it for me. The teacher said the correct answer is 3+2y/7-4y. How is that the answer. Below is what you did earlier 3/(y+2) / (7/y-4)) = 3/(y+2) * (y-4)/7 = (3y-12)/(7y+14) or 3(y-4)/[7(y+2)]
