How did the Red Summer shift the way black people responded to violence?

The racist attacks in 1919 were widespread, and often indiscriminate, but in many places, they were initiated by white servicemen and centered upon the 380,000 black veterans who had just returned from the war. “Because of their military service, black veterans were seen as a particular threat to Jim Crow and racial subordination,” notes a report by the Equal Justice Initiative

Explanation: I hope I helped :)

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
