2•5у/3 + 24 = 3у + 36 10у/3 - 3у = 36 - 24 10у/3 - 9у/3 = 12 у/3 = 12 у = 12 • 3 у = 36 лет сыну сейчас.
х = 5у/3 х = 5•36/3 х = 60 лет отцу сейчас.
ответ: 60 лет. Я
Б. 1) 3+3+3 = 9 лет - на столько увеличится суммарный возраст ребёнка, матери и отца через три года. 2) 108 - 9 = 99 года - суммарный возраст ребёнка, матери и отца сейчас. 3) 4 + 14 + 15 = 33 части составляют суммарный возраст ребёнка, матери и отца. 4) 99 : 33 = 3 года соответствует одной части. 5) 3 • 15 = 45 дет отцу сейчас. 6) 45 + 15 = 60 лет будет отцу через 15 лет.
