Which statements are true about the ordered pair (10, 5) and the system of equations? { 2x−5y=−5
{ x+2y=11

Select each correct answer.

The ordered pair (10, 5) is a solution to the first equation because it makes the first equation true.

The ordered pair (10, 5) is a solution to the second equation because it makes the second equation true.

The ordered pair (10, 5) is not a solution to the system because it makes at least one of the equations false.

The ordered pair (10, 5) is a solution to the system because it makes both equations true.
