What’s one foreign policy challenge we face today

The 45th President of the United States, Donald J. Trump, has inherited a number of daunting foreign policy challenges spanning the globe from the Middle East through East Asia.

Trump tweeted this morning that "THE WORK BEGINS!" yet many of his top foreign policy positions have yet to be confirmed by the Senate, including CIA Director and Secretary of State.

Explanation:

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
