The correct answer is letter B

Explanation:

History began to change in July 1863, when the two bloodiest clashes in the conflict took place. The forces of the South, when attempting to invade the North, were detained in Gettysburg, Pennsylvania. And Union forces captured the Confederate fortress in Vicksburg, Mississippi. It was during a ceremony at Gettysburg that Lincoln delivered a famous speech in which he promised that "in this nation, under the grace of God, there will be a rebirth of freedom; and the government of the people, by the people and for the people will not perish on Earth" . Abraham Lincoln's dream of a unified country was finally secured. But, unfortunately, Lincoln himself did not survive to enjoy the peace so hard won. On April 14, 1865, while attending a performance at the Ford Theater in Washington, he was murdered by John Wilkes Booth (1838-1865), an unemployed enslaving actor and sympathizer with the Confederate cause.

a is correct

hope this let me know if it is right

1.3x - 2 - (3.3x + 5) = 2x + 1

1.3x - 2 - 3.3x - 5 = 2x + 1

-2x - 7 = 2x + 1

-7 = 4x + 1

-8 = 4x

x = -2
