Explanation: I think

A) A chance to a better life

Explanation:

The conquest of the new western lands was a way of escaping the overpopulation that  took place on the east coast of the country, which created social tensions, due to the lack of opportunities. Therefore, the main reason for migrating to these lands It was to look for a better life in a territory to explore.

the

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
