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 :)
