When the republican party formed in the 1850's, its support for free labor meant that? a. people worked for free. b. white men did not have to compete for jobs. c. slavery spread in the south. d. people were hired without restrictions.

b. white men did not have to compete for jobs.

b

Explanation:

white men did not have to compete for jobs.

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
