you can set up some equations for this one:

adult tickets = a

child tickets = c

a+c = 12

10a+5c = 100

a = 12 - c

10(12 - c) + 5c = 100

120 - 10c + 5c = 100

120 - 5c = 100

-5c = -20

c = 4

a = 12 - 4

a = 8

so, Quentin bought **4 child tickets **and **8 adult tickets.**

hopefully you can follow what i did with the equations above! please correct me if i am wrong:)
