Bonjour

a)−3+ x =7

x = 7 + 3

x = 10

b)3x +7x =50

10x = 50

x = 50/10

x = 5

c)5/3x= 4

5/3x = 12/3

5x = 12

x = 12/5

d)6x −7 =8

6x = 8 + 7

6x = 15

x = 15/6

x = 5/2

e)2x − 11=7x +4

2x - 7x = 4 + 11

- 5x = 15

x = - 15/5

x = - 3

f)6−3x = 15+4x

- 3x - 4x = 15 - 6

- 7x = 9

x = - 9/7.
