option
6,8
8,6
7,7
9,5​

Answer 1

Answer:

option B, 8,6

Step-by-step explanation:

Add both equations :-

x + y = 14

x - y = 2

2x + y - y = 16

2x = 16

x = 16 ÷ 2 = 8

If x = 8, then y = 14-8=6

so , x = 8

y = 6

Answer 2

Answer:

6,8

Step-by-step explanation:

x+y=14 (1)

x-y=2 (2)

x=2+y (3)

2+y+y=14

2+2y=14

2y=14-2

2y=12

y=12÷2

y=6

x-6=2

x=2+6

x=8
