A) 12
B) 11
C) 13
D) 10
Correct Answer: A
Solution :
The system of equations represents coincident line, it \[\frac{{{a}_{1}}}{{{a}_{2}}}=\frac{{{b}_{1}}}{{{b}_{2}}}=\frac{{{c}_{1}}}{{{c}_{2}}}\] i.e. \[\frac{3}{6}=\frac{4}{8}=\frac{6}{k}\] \[\Rightarrow \] \[4k=6\times 8\] \[\Rightarrow \] \[k=\frac{48}{4}=12\]You need to login to perform this action.
