Ответ:
\(x : 19 = 24\)
\(x = 24 \cdot 19 = 456\).
\(252 : x = 14\)
\(x = 252 : 14 = 18\).
\((x + 8) : 9 = 12\)
\(x + 8 = 12 \cdot 9 = 108\),
\(x = 108 - 8 = 100\).
\(x : 9 - 8 = 12\)
\(x : 9 = 12 + 8 = 20\),
\(x = 20 \cdot 9 = 180\).
\(72 : (x - 6) = 12\)
\(x - 6 = 72 : 12 = 6\),
\(x = 6 + 6 = 12\).
\(72 : x - 6 = 12\)
\(72 : x = 12 + 6 = 18\),
\(x = 72 : 18 = 4\).
Ответ: 1) \(x = 456\); 2) \(x = 18\); 3) \(x = 100\); 4) \(x = 180\); 5) \(x = 12\); 6) \(x = 4\).
