pouvais vous m'aider pour l'exercice 33,34 et 35 svp ​

Bonjour,

33)

a)

x= 2-3

x= -1

b)

x= 2+3

x= 5

c)

x= 2/3

d)

x= 2*3

34)

a)

2x= 1-3

2x= -2

x= -2/2

x= -1

b)

2x= 1+3

2x= 4

x= 4/2

x= 2

c)

2x+6 = 1

2x= 1-6

2x= -5

x= -5/2

d)

2x-6 = 1

2x= 1+6

2x= 7

x= 7/2

35)

a )

x= 1/6 +1

x= 1/6 +6/6

x= 7/6

b)

3x = 4/3 +2

4x= 4/3 +6/3

x = 10/3

c)

2x/5 = 4/5 -1

2x/5 = 4/5 -5/5

2x/5 = -1/5

2x = -1/5 *5

2x = -5/5

2x= -1

x= -1/2

d)

3x/7 = -8 -4

3x/7 = -12

3x = -12*7

3x= -84

x = -84/3

x= -28
