Uruk was the world's first city, but, as you can see, many important cities sprung up in Mesopotamia soon thereafter. Why do you suppose this area promoted the founding and development of so many cities?

a is true because it know the force.

ps maybe give us more info?

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
