#x<7#

Explanation:

In a inequality you can add and subtract however you want to.

#5x+4<39#
Minus #4# both sides results in: #5x<35#

You can divide with a constant as long as its positive.

Dividing by #5# on both sides results in: #x<7#

Summary:
You can use a inequality just like a equation but you have to be very careful as sometimes you have to flip the inequality sign (if the operation you are applying is decreasing)
