Help me plzz people Which statement describes a social effect on the Civil War's end on Texas

Fewer Europeans immigrants came to Texas than before the war.

High casualty rates caused significant hardship to families.

African Americans were accepted as members of Texas society.

Workers received fair wages with the adoption of tenant farming.

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

i believe it's that they cared for people. hope this ! : )

what is the full question?
