Автор ответа: СанаМХ

(1450-50) = 700 руб. - стоит один

700+50 = 750 руб. стоит другой

Автор ответа: yulia318

Пусть первый сарафан стоит х рублей,
Тогда второй будет стоить х+50 рублей
Составим уравнение:
х+х+50=1450
2х+50=1450
2х=1450-50
2х=1400
х=1400:2
х=700, значит первый сарафан стоит 700 рублей
700+50=750(руб)-стоит второй сарафан

Ответ: 700 рублей; 750 рублей
