Why was it so difficult to pass laws in the late 1800s?

In the late eighteen hundreds, white Americans expanded their settlements in the western part of the country. They claimed land traditionally used by American Indians. The Indians were hunters, and they struggled to keep control of their hunting lands.

The federal government supported the settlers' claims. It fought, and won, several wars with Indian tribes. It forced the Indians to live on government-controlled reservations.

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
