Solve the system of equations for c, the number of children in the group.Answer by checkley71(8403)   (Show Source): You can put this solution on YOUR website!C+A=80 OR C=80-A C=3A NOW SET THESE 2 EQUATION EQUAL BECAUSE THEY BOTH EQUAL C. 3A=80-A 3A+A=80 4A=80 A=80/4 A=20 NUMBER OF ADULTS. 80-20=60 CHILDREN. PROOF. 3*20=80-20 60=60
