2/3 + X/5 < 4/15 SOLVE USING ADDITION AND MULTIPLICATION PRINCIPALS

Sorry, that's all wrong.  Here's what you do:


       X%2F5 + 2%2F3 < 4%2F15

Multiply every term by LCD = 15

 15·X%2F5 + 15·2%2F3 < 15·4%2F15

Simplify:

      3X + 10 < 4

Add -10 to both sides:

           3X < 4-10

           3X < -6

Divide both sides by 3

           3X%2F3 < %28-6%29%2F3

              X < -2

[As long as you divide or multiply only by positive
numbers, you don't flip the inequality sign].
