#-1 <= x-3 <=5#

You can break the inequality up into two parts, work with them separately, and combine them at the end.

#color(red)(-1 <= x-3 )<=5" "and" " -1 <= color(blue)(x-3 <=5)#

#color(red)(-1 <= x-3 )color(white)(........................................)color(blue)(x-3 <=5)#

Isolate x on the right side #color(white)(................)# isolate x on the left side

#color(red)(-1 +3 <= x )color(white)(........................................)color(blue)(x <=5+3)#

#color(white)(.........)color(red)(2<= x )color(white)(.........................................)color(blue)(x <=8)#

Now combine the two parts with one #x#

#color(white)(...............................)color(red)(2<= )x color(blue)(<=8)#
