%281%2F7%29y%2B3=%281%2F2%29y....if you have this, then
%281%2F7%29y%2B3=%281%2F2%29y.......add -%281%2F2%29y to both sides
%281%2F7%29y+-%281%2F2%29y+%2B3+=%281%2F2%29y+-%281%2F2%29y
%281%2F7%29y+-%281%2F2%29y+%2B3+=cross%28%281%2F2%29y%29+-cross%28%281%2F2%29y%29
%281%2F7%29y+-%281%2F2%29y+%2B3+=0.....add -3 to both sides

%281%2F7%29y+-%281%2F2%29y+%2B3+-3+=0-3
%281%2F7%29y+-%281%2F2%29y+%2Bcross%283%29-cross%283%29+=-3
%281%2F7%29y+-%281%2F2%29y++=-3......LCD for left side is 14, so multiply both sides by 14}
14%281%2F7%29y+-14%281%2F2%29y++=-3%2A14
cross%2814%292%281%2Fcross%287%29%29y+-cross%2814%297%281%2Fcross%282%29%29y++=-42
2y+-7y++=-42
+-5y++=-42
+y++=-42%2F-5

+y++=+8.4
