117. Решите уравнение: 1) x : 19 = 26; 2) 238 : x = 14; 3) (x + 7) : 8 = 9; 4) x : 8 + 7 = 9; 5) 48 : (x + 3) = 6; 6) 48 : x + 3 = 6.

1. \(x : 19 = 26\)
   \(x = 26 \cdot 19 = 494\).
2. \(238 : x = 14\)
   \(x = 238 : 14 = 17\).
3. \((x + 7) : 8 = 9\)
   \(x + 7 = 9 \cdot 8 = 72\)
   \(x = 72 - 7 = 65\).
4. \(x : 8 + 7 = 9\)
   \(x : 8 = 9 - 7 = 2\)
   \(x = 2 \cdot 8 = 16\).
5. \(48 : (x + 3) = 6\)
   \(x + 3 = 48 : 6 = 8\)
   \(x = 8 - 3 = 5\).
6. \(48 : x + 3 = 6\)
   \(48 : x = 6 - 3 = 3\)
   \(x = 48 : 3 = 16\).

Ответ: 1) 494; 2) 17; 3) 65; 4) 16; 5) 5; 6) 16.
