Explanation:

The war had an economic and social impact on the people of Arkansas.   About 3,519 were killed as a result of combat in the war.Only forty-two percent of the population lived on farms as Arkansas became increasingly urban. Arkansas population fell by almost 40,000 between 1940 and 1950 b/c of the war.

8 - (2a + 7) = a + 40     distribute/multiply - into (2a + 7)

8 - 2a - 7 = a + 40

1 - 2a = a + 40       add 2a on both sides

1 = 3a + 40         subtract 40 on both sides

-39 = 3a       divide 3 on both sides

-13 = a

[proof]

8 - (2a + 7) = a + 40

8 - (2(-13) + 7) = -13 + 40

8 - (-26 + 7) = 27

8 - (-19) = 27

8 + 19 = 27

27 = 27
