just plot the lines in a graph... the most suitable method..
now just see the area... on which side of L1 does tht area lie ..choose a point from that area and see the nature of sign u get on putting tht ordered pair...
repeat the same for L2...
now take intersection of the soln. u get.from both..
fro L1 ---- ( -INF. , 0) U ( 1/3, INF.) FRO L2 --- ( -INF ,-3 ) U ( 1, INF.)
Taking int.
L2 forms the range..
