    X < = 4

    Step-by-step explanation:

    -3x - 24< = - 36

    Make - 3x the subject, by carrying - 24 to the other side

    Note: Moving - 24 to the other side changes to + 24

    -3x < = - 36 + 24

    -3x < = - 12

    Minus cancels minus

    3x < = 12

    Divide both sides by 3, to get the value of x

    3x/3 < = 12/3

    x < = 12/3

    x < = 4

    Therefore, x equals to 4

    x ≥ 4

    Step-by-step explanation:

    To solve this inequality, we are going to follow the steps below;

    first add 24 to both-side of the inequality

    -3x - 24 ≤ - 36

    -3x - 24 + 24 ≤ - 36 + 24

    -24 + 24 will give us zero, hence our inequality becomes;

    -3x ≤ - 12

    Divide both-side of the inequality by - 3.

    You should note that whenever you are dividing both-side of inequality by a negative sign, the inequality sign will change, if it is "≤" it becomes"≥" and if it is "≥" it becomes "≤".

    -3x/-3 ≤ - 12/-3

    x ≥ 4
