Option a. Sarah Walker known as Madam C.J Walker was the first American woman to earn more than $1 million, making her the first female millionaire in the United States.

Explanation:

Born in Louisiana on December 23rd, 1867, Sarah Breedlove, known as Madam C.J Walker was an African-American entrepreneur, philanthropist and political and social activist, that became the wealthiest self-made woman in the United States, and the first ever millionaire of the country. Her fortune came mainly from a line of cosmetics and hair products she developed for African American women.

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
