Answer:

No. They do not have unique solution.

Step-by-step explanation:

2x+3y=9                             (1)

-4x-6y=2                             (2)


(1)*2,       and (2)*1 , you have:

4x+6y=18                            (1)

-4x-6y=2                              (2)


(1)+(2), you have:0=20 (wrong)

The equations do not have unique solution
