Which of these was a weakness of the Continental army at the start of the war? A. supply shortages

"List three weaknesses of the Americans at the start of the war. The Continental Army was very small and always short of soldiers. * Few Americans were trained for battle. The army was plagued by shortages of gums, gunpowder, food, and uniforms."

so the answer is A.

Explanation:

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

what are the options?
