The final table in Phase I of a Linear Programming Problem is given below:

	Basic     Variables	0          0          0           0             -1	Sol.
0		1         1           1      0           0    -1         0        -1       -1          1	5
-1			3
		-1         0        -1       -1           0	-3

Here 1a x is the artificial variable. Does this LPP have a feasible solution? Justify your answer.
