%282%2F3%29x+-+%281%2F2%29y+=+1
LCD = 6multiply by 6
%28%282%2A6%29x%29%2F%283%29-%28%28%281%2A6%29x%29%2F%282%29%29+=+6
4x-3y=6................1
...
%281%2F3%29x+-+%281%2F4%29y+=+1%2F2
LCD = 12 . multiply by 12
%28%281%2A12%29x%29%2F%283%29-%28%28%281%2A12%29y%29%2F%284%29%29+=+%281%2F2%29%2A12
...
4x-3y=6....................2

They are the same lines. There are infinitely many solutions.Consistent & dependant.
