    The answer to your question is 5 weeks

    Step-by-step explanation:

    Data

    Ryan Miles

    $150 $50

    each week = $40 each week = $60

    x = savings

    y = time in weeks

    Process

    1. - Write an equation for Ryan savings

    x = 40y + 150

    2. - Write an equation for Miles savings

    x = 60y + 50

    3. - Solve the system by Equality

    40y + 150 = 60y + 50

    - Solve for y

    40y - 60y = 50 - 150

    -20y = - 100

    y = - 100 / - 20

    y = 5

    4. - Conclusion

    After 5 weeks, they will have the same amount of money.
