I don't want the answer I want to know how you solve the problem!

A restaurant manager bought 20 packages

of bagels. Some packages contained 6 bagels

each, and the rest contained 12 bagels each.

There were 168 bagels in all. How many

packages of 12 bagels did the manager buy?

A 6

B 8

C 9

D 12

Say X packages have 12 bagels. Then 20 -X have 6 bagels.

6(20-X) + 12X = 168

6X = 168-120

Solve that for X.
