#-1/2<=x<=1#

Explanation:

Solve #abs(4x-1)<=3#

There are two parts to this answer.

#color(red)(4x-1<=3)# and #color(blue)(4x-1>=-3)#

#color(red)(4x<=4)#

#color(red)(x<=1)#


#color(blue)(4x-1>=-3)#

#color(blue)(4x>=-2)#

#color(blue)(x>=-2/4)#

#color(blue)(x>=-1/2)#

#color(purple)(-1/2<=x<=1)#
