In the given equation:

(3200 * 56 / 5) ÷ 5 × 123 = (Х / 124 × 45) × 7654 ÷ 9000

We can simplify the left side first:

(3200 * 56 / 5) ÷ 5 × 123
= (179,200 / 5) ÷ 5 × 123
= 35,840 ÷ 5 × 123
= 7,168 × 123
= 882,864

Now, we can simplify the right side:

(Х / 124 × 45) × 7654 ÷ 9000
= (Х * 45 / 124) × 7654 / 9000

We can set the two sides equal to each other and solve for Х:

882,864 = (Х 45 / 124) × 7654 / 9000
Х = 882,864 9000 / (45 * 7654 / 124)
Х = 1,546,740

Therefore, the value of Х is 1,546,740.
