How did people participate in the second great awakening?

1790-1840

The Second Great Awakening attracted hundreds of converts to new Protestant denominations thus led to a period of antebellum social reforms and emphasis on salvation by institutions. The awakening enrolled millions of new members leading to the formation of new denominations. The awakening was a reaction against deism, skepticism,  and rational Christianity through evangelism.

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
