Answer 1

Răspuns:

Explicație pas cu pas:

a = -3

b = 113

a + b = -3 + 113 = 110

a - b = -3 - 113 = -116

_____________

a = -105

a + b = 100

b = 100 - a = 100 - (-105) = 100 + 105 = 205

a - b = -105 - 205 = -310

_____________

a = 12

a - b = 7

b = a - 7 = 12 - 5 = 5

a + b = 12 + 5 = 17

_____________

a = -37

a - b = -25

b = a - (-25) = a + 25 = -37 + 25 = -12

a + b = -37 + (- 12) = -37 - 12 = -49

_____________

a = 0

a + b = -43

b = -43 - a = -43 - 0 = -43

a - b = 0 - (-43) = 0 + 43 = 43

_____________
