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

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

чет залагало, лучше перепиши с комента

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

(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
