Option E.
Statement 1 gives one equation and 2 variables so we can't solve it. Not sufficient.
Statement 2 is also one eq with 2 variables. Not sufficient.
Together - they are actually same eq's just rearranged.

Hi All,
We're asked for the value of X.
1) 5X + 3Y = 15
Fact 1 gives us just 1 equation to work with. Since there are no 'limitations' on the value of X or Y, X could be anything (positive, negative, 0, a fraction, etc.).
Fact 1 is INSUFFICIENT
2) Y = 5 - (5/3)X
Fact 2 also gives us just 1 equation to work with. Since there are no 'limitations' on the value of X or Y, X could be anything (positive, negative, 0, a fraction, etc.).
Since this equation is somewhat 'odd-looking', I'm going to re-write it here:
Y = 5 - (5/3)X
Y + (5/3)X = 5
3Y + 5X = 15
5X + 3Y = 15
Notice how this is the exact SAME equation that we were given in Fact 1...
Fact 2 is INSUFFICIENT
Combined, we still have just 1 equation (NOT 2 different equations), so X can still be any value.
Combined, INSUFFICIENT
Final Answer:
GMAT assassins aren't born, they're made,
