a special olympics event has 2 more boys than girls competing. the total number of participants is 1000. How many boys competed and how many girls competed?

Solution

let the number of girls be x and therefore we have the number of boys=x+2

we write the equation as x+(x+2)=1000

                                      2x+2=1000

                                        2x=1000-2=998

                                         x=998/2=499

the number of girls is 499 and the number of boys is 501
