Пошаговое объяснение:

1 5/6х - 2/3х + 0,25х = 1 5/6х - 2/3х + 1/4х =

1 10/12х - 8/12х + 3/12х = (1 10/12 - 8/12 + 3/12) * х = 1 5/12 * х = 1 5/12х

х = 6

1 5/12х = 1 5/12 * 6 = 17/12 * 6 = 17/2 * 1 =

17/2 = 8 1/2 или 8,5

6,12у + 1 2/5у - 0,32у = 6,12у + 1,4у - 0,32у =

(6,12 + 1,4 - 0,32) * у = 7,2 * у = 7,2у

у = 5

7,2у = 7,2 * 5 = 36
