Answer 1

Respuesta:

21 + x = 26

x = 26-21

x = 5

12 + x = 16

x = 16-12

x = 4

x - 2 = 10

x = 10+2

x = 12

x + 7 = 12

x = 12-7

x = 5

x + 15 = 28

x = 28-15

x = 13

x + 18 = 12

x = 12-18

x = -6

x - 13 = 24

x = 24+13

x = 37

x + 14 = -32

x = -32-14

x = -46

x + 2 = 14

x = 14-2

x = 12

x + 14 = 10

x = 10-14

x = -4

x + 19 = 21

x = 21-19

x = 2

x + 24 = 36

x = 36-24

x = 12

x + 18 = 9

x = 9-18

x = -9

x - 12 = 12

x = 12+12

x = 24
