3x + 7 = x - 15
First, make sure to subtract

from both sides.
Second, simplify 3x - x to get 2x, and then keep the 7.
Third, subtract

from both sides.
Fourth, simplify -15 - 7 to get -22.
Fifth, take the 2 and divide both sides by it, keeping the

by itself.
Sixth, since 11 goes into 2 to get 22, simplify the fraction to 11.

Answer:
x = -11

In 1882, Congress passed the Chinese Exclusion Act, which was a law that prohibited Chinese workers from immigrating to the United States for ten years. This act was designed to halt Chinese immigrants from coming to the United States. However, it also prohibited Chinese immigrants from becoming U.S. citizens.
Explanation:
In the given sentence “In 1882..” the sentence already conveys that the law was passed to bar Chinese workers from immigrating to the US for the next ten years. Thus it would be inappropriate to repeat “act was designed..”.
Hence the revised passage would look like as provided below-

After the railroad was completed, Chinese immigrants faced increasing amounts of prejudice and discrimination. Many native-born Americans felt that the Chinese were responsible for unemployment and decreasing wages. <u>In 1882, Congress passed the Chinese Exclusion Act, a law that prohibited Chinese workers from immigrating to the United States for ten years and becoming U.S. citizens.</u> The Chinese Exclusion Act was the first national legislation to restrict free immigration to the United States.
