Why is General Howe having trouble getting soldiers moved from New York?

But some success did occur in upstate New York. Gen. George Washington arrived in Cambridge on July 2, 1775, to officially take command of the new Continental forces. As he struggled to access and build a functioning army, he also had to contend with a lack of artillery among the Americans. Henry Knox, a book store owner in Boston, was given the task of retrieving the heavy munitions from Fort Ticonderoga. Knox’s successful journey – hauling thousands of tons of cannon by oxen through winter conditions from upstate New York to Boston – was nothing short of remarkable. The Americans finally had cannon to strike the British, but what to do with them?

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
