What effect did uncle toms cabin have on feeling about slavery in the United States ?

It brought slavery to life for many Northerners. It did not necessarily make these people devoted abolitionists, but the book began to move more and more Northerners to consider ending the institution of slavery. In 1862, Stowe met President Abraham Lincoln while she was visiting Washington, DC.

Explanation:

ok sorry the answer is a. by their religion

8 - (2a + 7) = a + 40     distribute/multiply - into (2a + 7)

8 - 2a - 7 = a + 40

1 - 2a = a + 40       add 2a on both sides

1 = 3a + 40         subtract 40 on both sides

-39 = 3a       divide 3 on both sides

-13 = a

[proof]

8 - (2a + 7) = a + 40

8 - (2(-13) + 7) = -13 + 40

8 - (-26 + 7) = 27

8 - (-19) = 27

8 + 19 = 27

27 = 27
