Question 314430: How do you solve 3x+14-x < 56+3x
Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!
You must get all the variable terms on one side, preferably the left side, and all the number terms on the opposite side.

Subtract 3x from each side:
3x+14-x-3x<56+3x-3x
14-x<56

Now, subtract 14 from each side:
14-14-x<56-14
-x<42

Now, this is the tricky step. Divide both sides by -1. When you mult or divide both sides by a negative number, you must reverse the inequality.
