-35,1 (9/13х-4/9)+45/9=-22,4 (5/16х-3/7)

-35,1 * 9/13 * х - 4/9 * (-35,1) + 45/9 = -22,4 * 5/16 * х - 3/7 * (-22,4);

-351/10 * 9/13 * х + 4/9 * 351/10 + 45/9 = -224/10 * 5/16 * х + 3/7 * 224/10;

-351 * 9/130 * х + 4 * 351/90 + 45/9 = -224 * 5/160 * х + 3 * 224/70;

-27 * 9/10 * х + 2 * 39/5 + 5 = -7 * х + 96/10;

-243/10 * х + 7 * х = 96/10 - 78/5 - 5;

-243 * х + 70 * х = 96 - 156 - 50;

-173 * х = - 110;

х = 110/173.

Ответ: х = 110/173.
