Solve using the addition and multiplication principles. 

 5 + 2x < 23 

The solution set is {x, x __ __} 

Type and inequality symbol, and then an integer or fraction.


 5 + 2x < 23

Add -5 to both sides

 5 + 2x < 23
-5        -5
 0 + 2x < 18
     2x < 18

Multiply both sides by 1%2F2

       %281%2F2%29%282x%29+%3C+18%2F2

             9
    %281%2Fcross%282%29%29%28cross%282%29x%29+%3C+cross%2818%29%2Fcross%282%29
             1
          x%3C9%2F1

          x%3C9

Solution set:

    { x,x%3C9 }
