Does the following system have a unique solution? why? 4x+10y=57 2x+5y=38

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.

there are no figures how am i supposed to answer this question
