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
For what value(s) of k, is the system of equations kx + 2y = 3 and 2x + y = 5 inconsistent ?
Assertion (A) : The system of linear equations 3x + 5y − 4 = 0 and 15x + 25y − 25 = 0 is inconsistent. Reason (R) : The pair of linear equations a₁x + b₁y + c₁ = 0 and a₂x + b₂y + c₂ = 0 is inconsistent if a₁/a₂ = b₁/b₂ ≠ c₁/c₂.
If the lines represented by equations 3x + 2my = 2 and 2x + 5y + 1 = 0 are parallel, then the value of m is :
