    Answer:

    Let x represents the week and y represents the amount of money.

    As per the given statement:

    Diego has $11 and begins $5 each week toward buying a new phone.

    ⇒               ……[1]

    It is also given that Lin $60 and begins spending $2 per week.

    ⇒               ….[2]

    when they have the same amount.

    equate [1] and [2] we get;

    Add both sides 2x we get;

    Subtract 11 from both sides we get;

    Divide both sides by 7 we get;

    x = 7

    Substitute the value of x = 7 in [1] we have;

    Therefore, at x= 7 week they have the same amount of money and they  have the amount at that time, $ 46
