C. In the parliamentary system, the head of the executive branch is also a member of the legislature, while in the federal system the head of the executive branch is elected separately.

Explanation:

Being a monarchy, the parliamentary system has a Queen or King that has virtually no power on legislature procedure but a lot of symbolic power, the "executive" or president of the U.K is not actually a figure, but the closest figure they have would be the prime minister which is chosen from the house of commons and it is often the leader of the party or parties in alliance that hold the most seats in the house of commons. So he is the head of the executive branch and a member of the legislature.

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
