3 1/4 х - 4 5/7 = 3 5/12 х - 3 3/14 решить уравнение

Решим уравнение 3 1/4 * х - 4 5/7 = 3 5/12 * х - 3 3/14.

3 1/4 * x - 3 5/12 * x = - 3 3/14 + 4 5/7;

3 * x + 1/4 * x - 3 * x - 5/12 * x = - 3 - 3/14 + 4 + 5/7;

1/4 * x - 5/12 * x = 1 + 5/7 - 3/14;

3/12 * x - 5/12 * x = 14/17 + 10/14 - 3/14;

(3 - 5) / 12 * x = (14 + 10 - 3) / 14;

-2/12 * x = (14 + 7) / 14;

-1/6 * x = (14 + 7) / 14;

-1/3 * x = (14 + 7) / 7;

-1/3 * x = 14/7 + 7/7;

-1/3 * x = 2 + 1;

-1/3 * x = 3;

-x = 3 * 3;

-x = 9;

x = - 9;

Ответ: х = - 9.
