#k < 27#

To solve this, first add #color(blue)14# to both sides of the inequality:
#k/3 - 14 quadcolor(blue)(+quad14) < -5 quadcolor(blue)(+quad14)#

#k/3 < 9#

Multiply both sides by #color(blue)3#:
#k/3 color(blue)(*3) < 9 color(blue)(*3)#

#k < 27#

This can be said as "#k# is less than #27#."

Here's a graph of it on a number line:

The open circle on #27# means that #27# is one of the solutions (and anything less than it).

Hope this helps!
