Which of the following archaeological digs was a Clovis kill site where mammoth remains were found alongside spear points?
A. the Domebo Canyon site
B. the Cooper bone bed site
C. the Salt Creek site
D. the Waugh site

the answers are a b and d

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
