Court decision and reasons What was the majority ruling of the court? Why did they rule this way

The Constitution states that the Supreme Court has both original and appellate jurisdiction. Original jurisdiction means that the Supreme Court is the first, and only, Court to hear a case. The Constitution limits original jurisdiction cases to those involving disputes between the states or disputes arising among ambassadors and other high-ranking ministers. Appellate jurisdiction means that the Court has the authority to review the decisions of lower courts. Most of the cases the Supreme Court hears are appeals from lower courts.

Explanation:

what do you mean

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
