How did the Civil War bring temporary and lasting changes to American society?

It freed all of the black men and ended the issue over slavery, but the South's economy was destroyed while the North's economy boomed.

Explanation:

The first three postwar amendments accomplished the most radical and rapid social and political change in American history: the abolition of slavery (13th) and the granting of equal citizenship (14th) and voting rights (15th) to former slaves, all within a period of five years. Some long-term effects that occurred after the Civil War were the abolishment of slavery, the formation of blacks' rights, industrialization and new innovations. The Northern states were not reliant on plantations and farms; instead they were reliant on industry.

overtime, the civil rights movement changed in a way that not only it benefited african-americans, but benefited other ethnicity's such as latinos, asians, or women too! that's why the results of the movement be called mixed.

the civil rights movement brought about tremendous changes. no longer were blacks denied the right to vote, to eat, shop, and swim where they , and more importantly, to attend integrated schools. despite its many accomplishments, however, the civil rights movement had its shortcomings. for example, many people, both young and old, lost their lives, homes, jobs, and families. still other individuals were so damaged by psychological trauma that they ceased being productive members of the community. the movement left intact the economic inequities that had contributed to the maintenance of segregation. and finally, racism remained alive and well long after the movement's end. like most movements of its kind, the civil rights movement left behind a mixed legacy of triumph and tragedy.

for this case we have the following equation:

we apply distributive property to the terms within parentheses.

subtracting 2 on both sides of the equation:
