#-2 < x#

Explanation:

Treat an inequality in exactly the same way as an equation, unless you multiply or divide by a negative, in which case the inequality sign changes around,

First you need to isolate the #x-# term.

#-3 <4x+5" "# subtract 5 from each side.

#-3 -5 < 4x +5 -5#

#-8/4 < 4/4x" "# now isolate #x: div4 #

#-2 < x#
