YALL PLEASE HELP1. During the Warring States period, many states mounted military
campaigns in attempts to conquer
other states. Consider the map.
Which states had to defend all of their
borders against potential invasion?
Which states had to defend a small
portion of their borders against
potential invasion?

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
