You can put this solution on YOUR website!
As far as I know, you can't solve this
You've got the same equation repeated
2x+-+y+=+3
6x+-+9+=+3y
multiply both sides of the 1st equation by 3
6x+-+3y+=+9
add 3y to both sides
6x+=+3y+%2B+9
subtract 9 from both sides
6x+-+9+=+3y
This is the 2nd equation, so you have 1 equation really
and 2 unknowns. Can't solve.
