In a concert, the ratio of the numbers of adults to the number of children is 3:4. If 60 more adults join in the concert, the number of adults will be twice the number of children. How many children are in the concert? thank you

Just as Denis posted (he used a = adult and c = children) : Can you substitute (2) in (1) now? Balarka .
