Will and Elvin had an equal number of bookmarks. After Will gave away 29 bookmarks and Elvin gave away 48 bookmarks, Will had 2 times as many bookmarks as Elvin. How many bookmarks did each have at first?
+526 Let's assume Will and Elvin had x no. of bookmarks at first.
After Will gave away 29 bookmarks and Elvin gave away 48 bookmarks, Will had 2 times as many bookmarks as Elvin.
So, according to question
x−29=2(x−48)
x−29=2x−96
⇒x=67
∴ Will and Elvin had 67 bookmarks each, at first.
~Hope this helps :)
