    Answer:

    Equation for the problem

    3x + 15 = 51 laps

    Hence

    She swims on

    Monday: 12 laps

    Wednesday : 12 laps

    Friday = 12 laps

    Step-by-step explanation:

    Ella swims four times a week at her club’s pool.

    We are told that:

    She swims the same number of laps on Monday, Wednesday, and Friday.

    Hence, the number rod times that she swims on Monday, Wednesday and Friday is represented by x

    Also, she swims 15 laps on Saturday. She swims a total of 51 laps each week. Equation for the problem

    = x + x + x + 15 = 51 laps

    3x + 15 = 51 laps

    Hence

    3x = 51 – 15

    3x = 36

    x = 36/3

    x = 12 laps

    Therefore, She swims on:

    Monday: 12 laps

    Wednesday : 12 laps

    Friday = 12 laps
