#2 > x > -3#

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!

#2 > x > -3# which can also be written as #-3 < x < 2#

Given: #-5 < 1-3x < 10#

Subtract 1 from all 3:

#-6 < -3x < 9#

Divide all 3 by -3:

#2 > x > -3#
