    Step-by-step explanation:

    Pete has already completed 27 missions. Pete plans to complete 3 missions per week

    Let x represents weeks

    Games completed = 3x + 27

    Sophie has only completed 13 missions. Sophie plans to complete 5 missions per week.

    Games completed = 5x + 13

    3x + 27 = 5x + 13

    27 – 13 = 5x – 3x

    2x = 14

    x = 7

    By the seventh week, they would have completed equal number of games,
