Which describes a reason that life in the chesapeake region and life in new england were different for early settlers?
a. the regions were settled at different times.
b. the indians were in the chesapeake but not in new england.
c. the climate and soil conditions of the two regions were different.
d. the people spoke different languages.

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
