Answer and Step-by-step explanation:
Simply solve for <em>x</em>. This is just like solving for <em>x</em> in an equation, so don't worry about the sign yet.
-2x + 4 < 16
<u>Subtract 4 from both sides.</u>
-2x < 12
<u>Add 2x and subtract 12 from both sides.</u>
-12 < 2x
<u>Divide 2 from both sides.</u>
<u>-6 < x</u> <-- This is the inequality
