Find the value(s) of \(c\) for the following pair of equations.
(i) \(-3x + 3y = 7\) and \(6cx - 3y = 1\), if the lines represented by these equations are intersecting at a unique point.
Answer:
\(c \neq\)
[Note: Enter the fraction without simplifying it]
(ii) \(7x + y - 5 = 0\) and \(cx - 2y - 8 = 0\), if the pair of equations has a unique solution.
Answer:
\(c \neq\)
