|x+3/5|-1/2=1/2
|x+3/5|=1/2+1/2
|x+3/5|=1
=>x+3/5=1
x=1-3/5
x=2/5
hay
x+3/5=-1
x=(-1)-3/5
x=-8/5
Vậy x=2/5 hay-8/5
1)vì |x-4/5|=3/4 =>x-4/5=3/4 hay x-4/5=-3/4 x=3/4+4/5 x= -3/4+4/5 x=31/20 x=1/20 vậy x=31/20 hay 1/20
6-|1/2-x|=2/5
|1/2-x|=6-2/5
|1/2-x|=28/5
=>1/2-x=28/5
x=1/2-28/5
x=-51/10
hay
1/2-x=-28/5
x=1/2-(-28/5)
x=61/10
vậy x=-51/10hay61/10
