First, let's isolate the absolute value term by adding 1 to both sides of the equation:
|10x - 1| = 19
Now we can split the equation into two cases:
Case 1: 10x - 1 = 19
Solve for x:
10x = 20
x = 2
Case 2: -(10x - 1) = 19
Solve for x:
-10x + 1 = 19
-10x = 18
x = -18/10
x = -9/5
So the solutions to the equation are x = 2 and x = -9/5.
Therefore, the correct choice is:
OA x = 2,-9/5
Solve the absolute value equation. |10x - 1| - 1 = 18 Select the correct choice below, and fill in the answer box if necessary.
