Question

How do I find the solution set of |2x – 3| – 10 = –1?

Answer 1

First isolate your absolute value part.

Answer 2

Like so:

|2x - 3| - 10 = -1
|2x - 3| = 9

From here you do both signs for the right side of the equation. Positive and negative.

2x - 3 = 9
2x = 12
x = 6

2x - 3 = -9
2x = -6
x = -3

So the values that are valid for x are: -3 and 6
