Let l be the number of CDs she sold last week.
Let t be the number of CDs she sold this week.
The first equation can be written as l = 3t + 6, because last week she sold 6 more than 3 times the number of CDs she sold this week.
The second equation can be written as l + t = 110, because she sold a total of 110 CDs over the 2 weeks.
So, the system of equations is:
l = 3t + 6
l + t = 110
Let t be the number of CDs she sold this week.
The first equation can be written as l = 3t + 6, because last week she sold 6 more than 3 times the number of CDs she sold this week.
The second equation can be written as l + t = 110, because she sold a total of 110 CDs over the 2 weeks.
So, the system of equations is:
l = 3t + 6
l + t = 110
