    Answer:

    a number that is substituted in an inequality that makes the inequality a true statement.

    EXAMPLE :

    x + 2 < 7  ;  x= 4

    1) substitute 4 into the inequality

    4 + 2 < 7

    2) solve ( add 4 and 2 together )

    6 < 7

    the number 4 is a solution to the inequality because 6 < 7 is true.
