An equation is formed of two equal expressions. The number of rounds of bingo for which the cost of a child and an adult will be equal is 3.
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of rounds played be represented by x.
Given the rounds of bingo costs the same for an adult and a child for x number of games, therefore,
13 + 2x = 10 + 3x
13 - 10 = 3x - 2x
3 = x
Hence, the number of rounds of bingo for which the cost of a child and an adult will be equal is 3.
