4 17/18х+1 3/8=12-(6 1/6+3/4) решите уравнение плиз

(4 * 18 + 17)/18 * х + (1 * 8 + 3)/8 = 12 - ((6 * 6 + 1)/6 + 3/4);

(72 + 17)/18 * х + (8 + 3)/8 = 12 - ((36 + 1)/6 + 3/4);

89/18 * х + 11/8 = 12 - (37/6 + 3/4);

89/18 * х + 11/8 = 288/24 - (148/24 + 18/24);

89/18 * х + 11/8 = (288 - 148 - 18)/24;

89/18 * х = 122/24 - 3/24;

х = 119/24 * 18/89 = (119 * 18)/(24 * 89) = (119 * 3)/(4 * 89) = 357/356.

Ответ: х = 357/356.
