Subsequently, the number of children can be written in terms of x as "2x + 2". (Each adult brings 2 children and one of the adults brought 2 extra children) Now multiply the number of adults and children with their corresponding prices and equate that to 60. That is "2 (2x + 2) + 4x = 60".Instead of dividing both sides by 210, you could have decided to distribute the 210. And then you would have ended up with-- let me do another alternate way of doing it. 210 times t minus 5 times 210.
