Пошаговое объяснение:

Д)

-1/6 - (-х) = 1/2

-1/6 + х = 1/2

х = 1/2 - (-1/6)

х = 1/2 + 1/6

х = 3/6 + 1/6

х = 4/6

х = 2/3

е)

х - (-1/4) = 2/3

х + 1/4 = 2/3

х = 2/3 - 1/4

х = 8/12 + 3/12

х = 11/12

ё)

-х + (-1/7) = -3/5

-х - 1/7 = -3/5

-х = -3/5 + 1/7

-х = -21/35 + 5/35

-х = -16/35

х = 16/35

ж)

у - (-2,3) = 0,5

у + 2,3 = 0,5

у = 0,5 - 2,3

у = -1,8

з)

-23,5 + (-у) = 5,2

-23,5 - у = 5,2

у = -23,5 - 5,2

у = -28,7
