Answer 1

Respuesta:

x + 2 = 6

x = 6 - 2

x = 4

x + 8 = 15

x = 15 - 8

x = 7

y +9 = 43

y = 43 - 9

y = 34

5 + x = 7

x = 7 - 5

x = 2

y + 74 = 183

y = 183 - 74

y = 109

y + 15 = 12 + 8

y = 12 + 8 - 15

y = 5

x + 2.5 = 7.8

x = 7.8 - 2.5

x = 5.3

x + 3.9 = 14.6

x = 14.6 - 3.9

x =10.7

y + 15 = 20 + 40

y = 20 + 40 - 15

y = 45
