Пошаговое объяснение:1) Пусть второй рабочий изготовил x деталей, тогда первый - 3x деталей, а третий- (x+15) деталей. 2)Составляем и решим уравнение:

x+3x+x+15=100

5x+15=100

5x=100-15

5x=85

x=85:5

x=17 деталей -сделал 2-ой рабочий

3x=51 деталь -сделал 1-ый рабочий

x+15= 17+15=32 детали -сделал 3ий рабочий
