Answer:

No

Step-by-step explanation:

4x+10y=57                                    (1)

2x+5y=38                                      (2)


(1)*1;     (2) * (-2), you have


4x+10y =57                                   (1)

-4x-10y =-76                                  (2)


(1)+(2), you have:


0= -=19  (wrong)

The equations do not have the solution .

The system does not have a unique solution.
