The Battle of Yorktown
was perhaps the most important event of the American Revolution. It led to the Patriots’ overall victory. General
and his troops attacked General
British army for almost three weeks nonstop, until the British surrendered. The
naval fleet helped the Continental army secure this victory.

can you tell me what is it

they thoght they were going to nuke each other

macon. i believe thats the answer

sorry if im wrong.

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
