Shaun and anna have a collection of tennis balls. shaun said if anna gives him 4 of her balls they would have an equal number; but if shaun would give anna 4 of his balls, anna would have 2 times as many balls as shaun. how many balls does anna have?

Ok so, Shaun should have 4 balls and Anna should have about 12. So, if Shaun takes 4 of Anna's tennis balls then he would have 8, but if Anna takes 4 of Shaun's balls she would get 16. That means the number of tennis balls she has right now would be 12, and if she gets 4 of Shaun's balls she would have 16. Hope This Helps! :)
