When the president provides leadership on a important moral issue he is acting as the nations

When the president provides leadership on an important moral issue, he is acting as the nations Chief Citizen.  The president is expected to extend moral authority and provide reassurance that citizens live in a righteous Nation, even when it works in ways inimical to the professed national values of the country. As the chief citizen, the president should represent the people and work for the public interest. The president as the Chief Citizen must strive to embody American ideals, serve the interest of the nation and act in the Nation's best interest. When there is a tragedy, the president works is to tell, inspire, and comfort the people of America.

simplify brackets

8 - 2a - 7 = a + 40

simplify 8 - 2a - 7 to -2a + 1

-2a + 1 = a + 40

add 2a to both sides

1 = a + 40 + 2a

simplify a + 40 + 2a to 3a + 40

1 = 3a + 40

subtract 40 from both sides

1 - 40 = 3a

simplify 1 - 40 o -39

-39 = 3a

divide both sides by 3

-39/3 = a

simplify 39/3 to 13

-13 = a

switch sides

a = -13

number 1 is a)
