What best described the supreme court reasoning in declaring the civil rights act of 1875 unconstitutional

The Supreme Court, in an 8–1 decision, declared sections of the act unconstitutional in the Civil Rights Cases on October 15, 1883. ... The Court also held that the Thirteenth Amendment was meant to eliminate "the badge of slavery," but not to prohibit racial discrimination in public accommodations.

the answer is false.

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
