Asked by Cody
I can't seem to do this problem. And my grade is riding on it. Can someone please help? I don't know how to solve it. Can someone help me by telling me what I'm doing wrong?
The problem is 3y = 2x + 12
My Work:
0=2x+ 12
--------
2 2
x=6
You cannot solve this equation. It has 2 unknowns.

The problem is 3y = 2x + 12
My Work:
0=2x+ 12 How and/or why did you eliminate y from the equation.
--------
2 2
x=6
A ssuming you are seeking integer answers.
1--3y - 2x = 12
2--Dividing through by 2 yields y + y/2 - x = 6
3--y/2 must be an integer k mking y = 2k
4--Substituting back into (1)0 yields 6k - 2x = 12 making x = 3k - 6
5--CLearly, without any other conditions imposed by the problem statement, there are an infinite number of answers.
6--k...0...1...2...3...4...5...6..
...x..-6..-3...0...3...6...9..12..
...y...0...2...4...6...8..10..12..
