Answer:

[ Please see the attachment to understand well. ]

Step-by-step explanation:

Let the missing numbers be x

Question A.

x - 8 = 15

x = 15+8

x = 23

[23 - 8 = 15]

Question B.

x - 9 = 15

x = 15+9

x = 24

[24 - 9 = 15]

Question C.

x - 2 = 15

x = 15+2

x = 17

[17 - 2 = 15]

Question D.

x + 4 = 15

x = 15 - 4

x = 11

[11 + 4 = 15]

Question E.

x + 9 = 15

x = 15 - 9

x = 6

[6 + 9 = 15]

Question F.

6 - x = 15

-x = 15 - 6

-x = 9

x = -9

[6 - (-9) = 15]

[6+9 = 15]

Question G.

10+x = 15

x = 15 - 10

x = 5

[10+5 = 15]

Question H.

x + 3 = 15

x = 15 - 3

x = 12

[12+3 = 15]

Hope it's helpful !
