7. Решите уравнение: a) (x + 2 9/11) - 4 10/11 = 1 4/11; б) (8 5/27 - x) - 2 25/27 = 1 25/27

а) (x + 2 9/11) - 4 10/11 = 1 4/11 x + 2 9/11 = 1 4/11 + 4 10/11 x + 2 9/11 = 5 14/11 x + 2 9/11 = 6 3/11 x = 6 3/11 - 2 9/11 x = 5 14/11 - 2 9/11 x = 3 5/11 б) (8 5/27 - x) - 2 25/27 = 1 25/27 8 5/27 - x = 1 25/27 + 2 25/27 8 5/27 - x = 3 50/27 8 5/27 - x = 4 23/27 x = 8 5/27 - 4 23/27 x = 7 32/27 - 4 23/27 x = 3 9/27 x = 3 1/3
