Bonjour,
----------------------------------------------------------------------------------------------------------------------
1. |x-1| = 3
x-1 = 3
x = 3 + 1
x = 4
2. |x+2| = 6
x = 6-2
x = 4
3. |x-[tex]\frac{3}{4}[/tex]|= [tex]\frac{1}{6}[/tex]
x = [tex]\frac{1}{6}+\frac{3}{4}[/tex]
x = [tex]\frac{1*2}{6*2}+\frac{3*3}{4*3}[/tex]
x = [tex]\frac{2}{12}+\frac{9}{12}[/tex]
x = [tex]\frac{11}{12}[/tex]
4. |x+4| = -2
x+4 = -2
x = -6

Au plaisir d'avoir aidée :)
