Question

Hay que determinar el valor de cada incógnita
n + - 47 = 30
d + 30 = 39
- 75 - r = 11
0 - s = 83
39 - p = - 29

Answer 1

n + - 47 = 30

n -7 = 30

n =  30 + 7

n =37

d + 30 = 39

d = 39 - 30

d = 9

- 75 - r = 11

-75 - 11 = r

-86 = r

0 - s = 83

0 - 83 = s

-83  = s

39 - p = - 29

39 + 29 = p

68 = p
