Svp j'arrive pas a trouver les résultats

Sagot :

Bonsoir,

a. 5x = 3x + 3

5x-3x = 3

2x= 3

x= 3/2 = 1,5

b. 8x = 12x + 4

-4 = 12x -8x

-4 = 4x

x= -4/4 = -1

c. 4 – 7y = 10y

4 = 10y +7y

4 = 17y

y = 4/17

d. 7x + 1 = - 4 - x

7x+x = -4 -1

8x =-5

x= -5/8

e. 2 + 3x = 7 - 3x

3x+3x = 7 -2

6x = 5

x= 5/6
