#2 > x > -3#

Explanation:

Step one: subtract both sides by 1

#-5color(red)((-1))< 1 - 3x color(red)((-1))< 10 color(red)((-1))#

this gives us
#color(green)(-6) > color(green)(-3x) > color(green)(9)#

Now divide both sides by -3

#color(green)(2) < color(green)(x) < color(green)(-3x)#

There you go!
