Question

which one of the following pair of linear equations has inconsistent solution ? 15 13 27 (A) 15x + 13y + 27 = 0 and 5x+y+ = = 0 2 2 2 - (B) 30x + 26y + 54 = 0 and 20x + 13y + 5 = 0 (C) 15x + 13y + 27 = 0 and 45x + 39y + 29 = 0 (D) x + 5y + 10 = 0 and 2x + 10y + 20 = 0 (E) None of these​

Answer 1

Answer:

Option C

$15x + 13y + 27 = 0$

$45x + 39y + 29 = 0$

as

15/45 = 13/39 ≠ 27/29
