What happened when the indians decided to fight against the settlers moving onto the frontier?

Pontiac’s Rebellion

It started when Native Americans, offended by the policies of British General Jeffrey Amherst, attacked a number of British forts and settlements. It was started by a loose confederation of elements of Native American tribes, primarily from the Great Lakes region, the Illinois Country, and Ohio Country

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
