Q78.The number of values of k for which the system of linear equations (k + 2)x + 10y = k & kx + (k + 3)y = k โ1 has no solution is (1) 1 (2) 2 (3) 3 (4) 4
What This Question Tests
The question assesses the ability to apply the conditions for a system of two linear equations to have no solution, which involves setting up and solving equations based on the ratios of coefficients.
Concepts Tested
Formulas Used
For a_1x + b_1y = c_1, a_2x + b_2y = c_2 to have no solution: a_1/a_2 = b_1/b_2 โ c_1/c_2
