Step-by-step explanation:

The system of equations:

cx + 3y = c - 3 ... (i)

12x + cy = c ... (ii)

Multiplying (i) by c and (ii) by 3 gives;

c²x + 3cy = c² - 3c ... (i)

36x + 3cy = 3c ... (ii)

(i) - (ii) gives;

c²x - 36x + 0 = c² - 3c - 3c

c²x - 36x = c²

c²x - c² = 36x

c²(x - 1) = 36x

c² =

If  c = -2 then;

(-2)² = 4 = , 4x - 4 = 36x , 32x = -4 , x =

If c = 2  then;

2² =

If c = 6 then;

6² = 36 = , 36x - 36 = 36x, 36x - 36x = 36 , x (36 - 36) = 36 , x(0) = 36 , x =   = undefined or infinitely many solutions.

Hence the system of equations given above will have infinitely many solutions if the value of c is 6.
