226. Решите уравнение: 1)x+3,72 = 8; 2)14,6-x = 5,293; 3)x12,956 = 11,034; 4) (28-x) +35,6 = 43,214.

Решение:

1. \( x + 3,72 = 8 \)
   \( x = 8 - 3,72 \)
   \( x = 4,28 \)
2. \( 14,6 - x = 5,293 \)
   \( x = 14,6 - 5,293 \)
   \( x = 9,307 \)
3. \( x \cdot 12,956 = 11,034 \)
   \( x = \frac{11,034}{12,956} \)
   \( x \approx 0,8517 \)
4. \( (28 - x) + 35,6 = 43,214 \)
   \( 28 - x = 43,214 - 35,6 \)
   \( 28 - x = 7,614 \)
   \( x = 28 - 7,614 \)
   \( x = 20,386 \)

Ответ: 1) 4,28; 2) 9,307; 3) ≈ 0,8517; 4) 20,386.
