Question

РІВНЯНЯ 64-(3Y+8Y+Y)/40=

Answer 1

64 - (3у + 8у + у)/40 = 36

12у/40 = 64 - 36

12у/40 = 28

12у = 28 * 40

12у = 1120

у = 1120 : 12

у = 93 1/3

Проверка: 64 - (3 * 280/3 + 8 * 280/3 + 280/3) : 40 = 36

                  64 - (280 + 746 2/3 + 93 1/3) : 40 = 36

                  64 - 1120 : 40 = 36

                  64 - 28 = 36

                  36 = 36

Ответ: у = 93 1/3.
