    Answer: The system of equations for this situation are

    l = 3t + 6

    I + t = 110

    Step-by-step explanation:

    Let l represent the number of CDs she sold last week.

    Let t represent the number of CDs she sold this week.

    Last week she sold 6 more than 3 times the number of CDs that she sold this week. This would be expressed as

    l = 3t + 6

    Ms. Kitts sold a total of 110 CDs over the 2 weeks. This would be expressed as

    I + t = 110
