Step-by-step explanation:
|2x - 5| = 4
There are two solutions to the absolute value equation, one positive and one negative
2x - 5 = 4 and 2x - 5 =- 4
Add 5 to all sides
2x - 5+5 = 4+5 or 2x - 5+5 =- 4+5
2x = 9 or 2x = 1
Divide each side by 2
2x/2 = 9/2 2x/2 = 1/2
x = 9/2 x = 1/2
x = 1/2 or x = 4/5
