При входе в главный город страны к ним присоединилось несколько Болтунов, а по дороге во дворец-еще 200 Болтунов. Перед входом во дворец Стеллы 400 Болтунов ушли, а 100 пришли. Сколько Болтунов присоединилось к Элли и ее друзьям при входе в город, если во дворец вместе с ними вошли 300 жителей Розовой страны?

Answer 1

допустим ,что это число 600. То 600+200=800
800-400=400
400-100=300
все сходится их было 600 

Answer 2

(x+200)-400+100=300

x+200-400=200

x+200=600

x=600-200

x=400

Problem Analysis

The problem states that Ellie and her friends went to the Pink Land to meet the kind sorceress Stella. On their way to the main city, some Boltuns joined them, and on the way to the palace, an additional 200 Boltuns joined them. Before entering Stella's palace, 400 Boltuns left, and 100 Boltuns arrived. We need to determine how many Boltuns joined Ellie and her friends when they entered the city, given that 300 residents of the Pink Land entered the palace with them.

Solution
