Assertion (A) : The system of linear equations $\displaystyle 3 x-5 y+7=0$ and $\displaystyle -6 x+10 y+14=0$ is inconsistent.
Reason (R) : When two linear equations don't have unique solution, they always represent parallel lines.
Official answer
(C)
Assertion (A) is true, but Reason (R) is false.
