What major contribution did confucius make to the cultural development of china?

The essence of Confucius' teachings to the Chinese society is condensed in good conduct in life, good governance of the State (charity, justice and respect for the hierarchy), care for tradition, study and meditation. The maximum virtues are: tolerance, kindness, benevolence, love of neighbor and respect for the elderly and ancestors. If the prince is virtuous, the subjects will imitate his example, following the model ruler / subject, father / son, and so on. A prosperous society will only be achieved if these relationships are maintained in full harmony. The basis of the Confucian doctrine is to recover the ancient sages of Chinese culture and influence the customs of the people.

simplify brackets

8 - 2a - 7 = a + 40

simplify 8 - 2a - 7 to -2a + 1

-2a + 1 = a + 40

add 2a to both sides

1 = a + 40 + 2a

simplify a + 40 + 2a to 3a + 40

1 = 3a + 40

subtract 40 from both sides

1 - 40 = 3a

simplify 1 - 40 o -39

-39 = 3a

divide both sides by 3

-39/3 = a

simplify 39/3 to 13

-13 = a

switch sides

a = -13
