Answer:

D. X=-7, X=9

Step-by-step explanation:

Isolate x on one side of the equation.

|x-1|=8

ABSOLUTE VALUE:

x-1=-8 and x-1=8

x-1=-8

x-1+1=-8+1 (First, add 1 from both sides.)

-8+1 (Solve.)

-8+1=-7

x=-7

x-1=8

x-1+1=8+1 (Add 1 from both sides.)

8+1 (Solve.)

8+1=9

x=9

x=-7, x=9

As a result, the correct answer is (D.) x=-7, x=9.
