You can put this solution on YOUR website! A+C=33 & 20A+8C=468
A=33-C NOW REPLACE "A" WITH (33-C) IN THE OTHER EQUATION & SOLVE FOR "C".
20(33-C)+8C=468
660-20C+8C=468
-12C=468-660
-12C=-192
C=-192/-12
C=16 ANSWER FOR THE NUMBER OF CHILDREN TICKETS SOLD.
A=33-16
A=17 ADULT TICKETS SOLD.
PROOF
20*17+8*16=468
340+128=468
468=468
