What concerns did colonists have related to representation in parliament?

Explanatio No taxation without representation" is a slogan originating during the 1700s that summarized one of 27 colonial grievances of the American colonists in the Thirteen Colonies, which was one of the major causes of the American Revolution. In short, many in those colonies believed that, as they were not directly represented in the distant British Parliament, any laws it passed affecting the colonists (such as the Sugar Act and the Stamp Act) were illegal under the Bill of Rights 1689, and were a denial of their rights as Englishmen.

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
