Which statements are true about the ordered pair (5, −6) and the system of equations? {x+y=−13x−y=21 select each correct answer. the ordered pair (5, −6) is a solution to the first equation because it makes the first equation true. the ordered pair (5, −6) is a solution to the second equation because it makes the second equation true. the ordered pair (5, −6) is not a solution to the system because it makes at least one of the equations false. the ordered pair (5, −6) is a solution to the system because it makes both equations true.

Step-by-step explanation:

The system of equations is given as

x+y =-13 and

x-y =21

Adding we get

2x=8 or x=4

Substitute in I equation to get

4+y =13

y =9

Hence soluton is (4,9)

So (5,-6) cannot be the solution as there is only one unique solution to the system and that is (4,9)

When we substitute (5,-6) we hae

x+y=-1 and x-y = 11

Both equations are not satisfied.

The ordered pair (5, −6) is not a solution to the system because it makes at least one of the equations false.

the correct answers i think are b. and d.

give me brainliest if it is correct!

i believe it is b and c. (side note, i got the same computer from k-12 lol i’m in 8th grade and this is my first year, will it get
