Решите уравнение: а) 1 1/3 – x = 2 5/6; б) -2 2/7 + x = -4 1/14.

a) 1 1/3 – x = 2 5/6

4/3 - x = 17/6

-x = 17/6 - 4/3

-x = 17/6 - 8/6

-x = 9/6

x = -9/6

x = -3/2

x = -1 1/2

б) -2 2/7 + x = -4 1/14

-16/7 + x = -57/14

x = -57/14 + 16/7

x = -57/14 + 32/14

x = -25/14

x = -1 11/14

Ответ: а) -1 1/2; б) -1 11/14
