For this case we have the following system of equations:

[tex]y = -6x + 2\\-12x-2y = -4[/tex]

We clear the value of "y" from the second equation:

[tex]-2y = -4 + 12x\\y = \frac {-4} {- 2} + \frac {12} {- 2} x\\y = 2-6x[/tex]

We match the equations:

[tex]-6x + 2 = 2-6x\\-6x + 6x = 2-2\\0 = 0[/tex]

Equality is fulfilled! For any value of "x" is always met.

Thus, the system has infinite solutions.

Answer:

Infinite solutions
