Question

Решите уравнение (5/6x+1/7)умножить на 42 = 82

Answer 1

(5/6x + 7/8x)*42 = 82
(20/24x + 21/24x)*42 = 8241/24х * 42 = 8241/24х = 82/42х = 82/42 : 41/24х = 82/42 * 24/41х = 8/7 = 1 1/7

Answer 2

5/6x + 7/8x)*42 = 82

(20/24x + 21/24x)*42 = 82

41/24х * 42 = 82

41/24х = 82/42

х = 82/42 : 41/24

х = 82/42 * 24/41

х = 8/7 = 1 1/7

Answer 3

чет залагало, лучше перепиши с комента

Answer 4

5/6x + 7/8x)*42 = 82

(20/24x + 21/24x)*42 = 82

41/24х * 42 = 82

41/24х = 82/42

х = 82/42 : 41/24

х = 82/42 * 24/41

х = 8/7 = 1 1/7
