(PLS HELP ME)How were the economic conditions for many Southern whites during and after
Reconstruction?
They were getting rich through factories and industry.
Many were poor, with limited chances to improve their conditions.
They were now richer than those from the North.
Through the efforts of Reconstruction they found themselves better off than
before the war.

(Many were poor, with limited chances to improve their conditions.)

Explanation: I did the quiz, hope I helped.

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
