bonjour

4x+8=12

4x=12-8

4x=4

x=4/4

x=1

4x+8=1/3

4x=1/3-8 (on simplifie)

4x=-23/3

x=-23/3*1/4

x=-23/12

Bonjour,

4x + 8 = 12
4x = 12 - 8 = 4
x = 4 ÷ 4 = 1

4x + 8 = 1/3
8/1 = ( 8 × 3 )/(1 × 3 ) = 24/3
4x + 24/3 = 1/3
4x = 1/3 - 24/3 = (-23)/3
x = (-23)/3 ÷ 4 = (-23)/3 × 1/4 = (-23)/12

Bonne journée :)
