Explanation:

The Hans dynasty followed the Qin dynasty and preceded the period of the Three Kingdoms in China from 206 BC. C. until 220 d. During the Han Dynasty, their kings adopted the teachings of the great philosophers of antiquity, Lao-Tse and Confucius. The government developed well, achieving territorial expansion. Education and writing were encouraged in the newly invented rice paper. A great exchange of merchandise was promoted by the Silk Road, which goes from the Pacific Ocean to Persia and India. China officially became a Confucian state and flourished internally: agriculture, handmade products and trade flourished, and the population reached 50 million. Meanwhile, the empire extended its cultural and political influence over present-day Vietnam, Central Asia, Mongolia and Korea before collapsing under a combination of internal and external pressures.

1.3x - 2 - (3.3x + 5) = 2x + 1

1.3x - 2 - 3.3x - 5 = 2x + 1

-2x - 7 = 2x + 1

-7 = 4x + 1

-8 = 4x

x = -2
