Answer:

x = 7 or x = -2

Explanation:

|2x − 5| = 9 and |2x − 5| = -9

|2x − 5| = 9

Add 5 to both sides

2x - 5 + 5 = 9 + 5

Simplify

2x = 14

Divide both sides by 2

2x / 2 = 14 / 2

|2x − 5| = -9

Add 5 to both sides

2x - 5 + 5 = -9 + 5

Simplify

2x = -4

Divide both sides by 2

2x / 2 = -4 / 2
