Sagot :

Bonjour

12x+-39=-94

12x = - 94 + 39

12x = - 55

x = - 55/12

-44x+(-48)=72

- 44x = 72 + 48

- 44x = 120

x = - 120/44

x = - 30/11

7x+50=51

7x = 51 - 50

7x = 1

x = 1/7

-22x+(-45)=-60

- 22x = - 60 + 45

- 22x = - 25

x = 25/22

47x+(-50)=-33

47x = - 33 + 50

47x = 23

x = 23/47

-33x+48=-62

- 33x = - 62 - 48

- 33x = - 110

x = 110/33

-35x+(-36)=68

- 35x = 68 + 36

- 35x = 104

x = - 104/35

2x+(-40)=87

2x = 87 + 40

2x = 127

x = 127/2

-11x+(-49)=86

- 11x = 86 + 49

- 11x = 135

x = - 135/11

-9x+(-32)=46

- 9x = 46 + 32

- 9x = 78

x = - 78/9

x = - 26/3.
