Question

решите уровнение 8 2/15-(х+3 5/14):5 5/8=7 1/3​

Answer 1

Ответ:

х = 1 1/7

Пошаговое объяснение:

8 2/15 - (х+3 5/14) : 5 5/8 = 7 1/3​

(х + 3 5/14) : 5 5/8 = 8 2/15 - 7 1/3

(х+3 5/14) : 5 5/8 = 12/15

х + 3 5/14 = 4/5 * 45/8

х + 3 5/14 = 9/2 = 4 1/2

х = 4 1/2 - 3 5/14

х = 1 2/14 = 1 1/7

Проверим:

8 2/15 - (1 1/7+3 5/14) : 5 5/8=7 1/3

8 2/15  -4 1/2 : 5 5/8 =7 1/3

8 2/15 - 9/2*8/45 = 7 1/3

8 2/15 - 4/5 = 7 1/3

7 5/15 = 7 1/3

7 1/3 = 7 1/3
