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

the flooding of the nile was not a perfect occurrence. this gave rise to the belief in the gods and a highly stratified social structure. at the top of the social structure were gods such as ra and osiris because the egyptians believed that they controlled the universe. the egyptians tried their best to the gods because if they were happy, then the nile would flood producing an abundance of crops and preventing famine. after the gods came the pharaohs in social status. the egyptian people believed the pharaoh to be a god in mortal form. they had absolute power over the dominion which required protection through the of government officials and soldiers. the rest of the people’s status went in the order of scribes, merchants, artisans, farmers, and finally slaves.
