решить уравнения с дробями

1)x = 18/30 - 4/30 - 6/30

x = 8/30

x = 4/15

2)(13/67 + 6/67) - x = 9/67

x = 13/67 + 6/67 - 9/67

x = 10/67

3) 10/15 + (5/15 - x) = 14/15

x = 10/15 + 5/15 - 14/15

x = 1/15

4) 34/60 + 8/60 + y = 41/60 + 16/60

y = 57/60 - 42/60

y = 15/60

y = 1/4

5) 64/70 -(x + 26/70) = 5/70

x = 64/70 - 26/70 - 5/70

x = 33/70

6)x + 27/46 = 35/46 + 2/46

x = 37/46 - 27/46

x = 10/46

x = 5/23
