Statement 1...
this means that y is either 2 or 6
so insufficient
Statement 2
x=1
insufficient...
both still the value of y can be either 2 or 6
Hence E

statement 1)
least common denominator is lowest multiple of denominator that denominators in question can go into.
in this case, they say x/y and 1/3 have lcd of 6. which mean that y has to go into 6. the only numbers that y could be are 2 and 6.
rest is cake.
