Why would the ship captain have intentionally covered up the diseased reality of the slaves in his control

I don't see your answers,but,I would say because of the controversy of it all,he doesn't want America to know that he is possibly bringing disease into the country,and,that the people he is selling them to would possibly not buy them because of the disease.

Hope this helps my dude and can I get brainliest my dude :D

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
