You can put this solution on YOUR website!
First of all, this problem doesn't have a solution. It is really
the same equation repeated twice. You can graph it, but you'd
be graphing just one line. Note this:
2x+%2B+4y+=+2
If you divide both sides by 2, you get
x+%2B+2y+=+1, which is the 2nd equation.
If they were parallel lines, they would not intersect, and
there still would be no solution, but you have the same
equation repeated.
