e is the unknown number: 6*e + 3 < 30        - 3     -3          * to remove + 3, subtract 3 from both sides 6*e        < 27 ÷6            ÷6          * to remove 6, divide 6 from both sides    e         < 4.5        * should be less than 4.5 let us assume that e = 4 6*e + 3 < 30 6*4 + 3 < 30 24  + 3 < 30 27 < 30   * this makes the inequality true or correct. if e = 4.5 6*4.5 + 3 < 30 27     + 3 < 30 30           < 30  * this inequality is false. 30 is not less than 30. For the inequality to be true at most 29 should be placed at the left side of the inequality sign.
