In order to maintain national security within its colonies in america, england constructed a series of forts along colonial boundaries for protection. true false

The statement is - True.

Once the colonies were formed in America, England immediately started making forts along the boundaries of the colonies in order to protect them. Initially, the forts were made along the coastline, as most of the colonies were there, and the main threat was coming through sea. Over time, as the colonies expanded, and the threat was becoming bigger on land as well, forts were built along the mainland borderlines as well, mostly because of the Spanish and the threat they posed, but also because of the French, as well as the Native Americans.

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
