For what value of k, the system of equations kx + 2y = 2 and 3x + y = 1 will be coincident?
A. 2
B. 3
C. 5
D. 6
Answer: Option D
Solution (By Examveda Team)
$$\eqalign{ & {\text{For coincident lines}} \cr & \frac{{{a_1}}}{{{a_2}}} = \frac{{{b_1}}}{{{b_2}}} = \frac{{{c_1}}}{{{c_2}}} \cr & \therefore \frac{k}{3} = \frac{2}{1} = \frac{2}{1} \cr & {\text{Hence, }}k = 3 \times 2 \cr & k = 6 \cr} $$This Question Belongs to Arithmetic Ability >> Coordinate Geometry
