At a UFO convention, there are 120 conference attendees. If there are 4 more male attendees than female attendees, how many male attendees are there?
Define a variable ** Let's assume the number of female attendees is x.
How many male attendees are there? ** The number of male attendees is x+4.
Write an equation ** The sum of male attendees and female attendees is x+x+4 = 120
Combine like terms ** 2x+4 = 120
Subtract 4 ** 2x = 116
How many female attendees are there? ** The number of female attendees is x=116/2 = <<116/2=58>>58
How many male attendees are there? ** The number of male attendees is 58+4 = <<58+4=62>>62
