Question

Реши уравнение: (3 9/14 +х)-2 5/14=6 7/14

Answer 1

(3 9/14 + х) - 2 5/14 = 6 7/14
3 9/14 + х = 6 7/14 + 2 5/14
3 9/14 + х = 8 12/14
х = 8 12/14 - 3 9/14
х = 5 3/14
---------------------------------------------
(3 9/14 + 5 3/14) - 2 5/14 = 6 7/14
8 12/14 - 2 5/14              = 6 7/14
                          6 7/14  = 6 7/14
