HELP PLEASE I WILL GIVE BRAINLIEST AND 35 POINTS!!!!!!!!!!!!!!!!!!!!!!!Which statements are true about the ordered pair (−1, 5)
and the system of equations?
{x+y=4x−y=−6
Select each correct answer.
The ordered pair (−1, 5) is a solution to the first equation because it makes the first equation true.
The ordered pair (−1, 5) is a solution to the second equation because it makes the second equation true.
The ordered pair (−1, 5) is not a solution to the system because it makes at least one of the equations false.
The ordered pair (−1, 5) is a solution to the system because it makes both equations true.

For this case, we perform the conversions:
First roll:
We make a rule of three to determine the number of "c" boxes that can be packed with 300 meters of adhesive tape.
1 -----------> 4.2
c -----------> 300
You can pack 71 boxes.
Second roll:
We make a rule of three to determine the number of "c" boxes that can be packed with 70 meters of adhesive tape.
1 -----------> 4.2
c -----------> 70
You can pack 16 boxes.
Third roll:
1 -----------> 4.2
c -----------> 50
You can pack 11 boxes.
Thus, in total you can pack
Answer:
98 boxes
