We can solve the system of equations to check the number of system of the solutions.

y=-6x+2 ...(1)

-12x-2y=-4 ...(2)

Substitute -6x+2 for y in equation (2). So,

-12x-2(-6x+2)=-4

-12x+12x-4=-4 (By distribution property).

-4=-4 (-12x and +12x has been cancel out).

Notice x has vanish from the above equation and we are left with -4=-4 which is correct.

So, the system has infinte number of solutions.
