Answer 1

Пошаговое объяснение:

5 1/20 * 8 = у - 6 3/10

101/20 * 8 = у - 6 3/10

808/20 = у - 6 3/10

-у = -6 3/10 - 808/20

-у = -6 3/10 - 40 8/20

-у = -6 3/10 - 40 4/10

-у = -46 7/10

у = 46 7/10

х - 8 3/4 * 11 = 24 13/16

х - 35/4 * 11 = 24 13/16

х - 385/4 = 24 13/16

х = 24 13/16 + 385/4

х = 24 13/16 + 96 1/4

х = 24 13/16 + 96 4/16

х = 120 17/16

х = 121 1/16

х + 7 1/9 * 27 = 197 4/15

х + 64/9 * 27 = 197 4/15

х + 64/1 * 3 = 197 4/15

х + 192 = 197 4/15

х = 197 4/15 - 192

х = 5 4/15

х + 10 3/12 * 4 = 44 5/6

х + 123/12 * 4 = 44 5/6

х + 123/3 = 44 5/6

х + 41 = 44 5/6

х = 44 5/6 - 41

х = 3 5/6
