Explain, if the United States was Justified to invade Cuba due to the War with Spain.

I believe that the United States was justified to invade Cuba due to the war with spain.

Explanation: I think this because if you just had a war, or are having a war with a country you cannot let them have a territory so close to the United states so that they can invade the country.

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

c. is the answer : ) (you may punch me if im wrong lol)
