Answer 1

Answer:

option B

Step-by-step explanation:

A.(2,3)

X=2. Y=3

2+3=5

B.(5,-1)

X=5. Y-1

5+(-1) in not equal to 5

C.(4,1)

4+1=5

D.(-1,-4)

(-1)+(-4)=5

Answer 2

Step-by-step explanation:

SINCE X+Y= 5

THEREFORE

(1)= 2+3=5. ✓

(2)= 5+(-1)= 4 ×

(3) = 4+1= 5 ✓

(4) =( -1)+(-4)= -5 ×

thus (2) and (4) are not the solution of X+Y=5
