Consider the system of linear equations
\(-\)x + y + 2z = 0
3x \(-\) ay + 5z = 1
2x \(-\) 2y \(-\) az = 7
Let S1 be the set of all a\(\in\)R for which the system is inconsistent and S2 be the set of all a\(\in\)R for which the system has infinitely many solutions. If n(S1) and n(S2) denote the number of elements in S1 and S2 respectively, then
