The system of equations x + 5 = 0 and 2x – 1 = 0, has

The number of solutions of the system of equations x = a, x = b (a ≠ b) is :

The value of m for which lines 14x + my = 20 and -3x + 2y = 16 are parallel, is :

The value of k for which the system of equations 3x – 7y = 1 and kx + 14y = 6 is inconsistent, is

The pair of equations 3x – 5y = 7 and –6x + 10y = 7 have

Assertion (A): If a₁/a₂ = b₁/b₂ ≠ c₁/c₂, the system is inconsistent. Reason (R): Such a system represents parallel lines.
