Multiply the first equation by 3: 3(2x-y) = 3(4) gives 6x-3y = 12. This is a direct application of the distributive property and multiplication property of equality.

Peking (now Beijing) was called the 'Forbidden City' because the Chinese Emperor's palace complex was restricted to the imperial family and their court. Ordinary people were forbidden from entering without special permission.

Factor out (1/10)^18: (1/10)^18(1 - (1/10)^2) = (1/10)^18(1 - 1/100) = (1/10)^18(99/100) = 99/(10^18 * 10^2) = 99/10^20. This uses exponent rules and factoring.

Japan is called the 'Land of the Rising Sun' because it is one of the first countries to see the sunrise each day due to its eastern location in the world. The name comes from Japan's position east of the Asian mainland, where the sun appears to rise from the Japanese islands.

Combined rate = 1/20 + 1/30 - 1/40 = (6+4-3)/120 = 7/120 tank per minute. Time to fill = 120/7 = 17 1/7 minutes. Pipe A fills at 5% per minute, B at 3.33%, while C empties at 2.5% per minute, giving a net fill rate of about 5.83% per minute.

Total work = 30 men × 20 days × 9 hours = 5400 man-hours. With 40 men: 5400/40 = 135 days total. Hours per day = 5400/(40×20) = 7.5 hours. The inverse proportion between men and hours (when days are constant) gives: (30×9)/40 = 7.5 hours per day.
