Solve the inequality below

-3x+72<105

X>-11

X is greater than - 11, so the answer is x>-11

So think the inequality symbol is like a equal sign. Now since 72 and 105 are like terms you combine them so you subtract 72-72=0 and you do the same thing to the other side so 105-72=33. Now rewrite - 3x-11.

P. S. Anytime you divide on both sides with a inequality the sign is flipped.
