Question

Solve: |2x - 1| - 2 = 7

Answer 1

ok so first u add 2 to both sides
|2x-1|=5
then youre doing 2 equations
2x-1= 5 2x-1=-5
2x=6. 2x=-4
x=3. x=-2

Answer 2

x =5

Explanation:

transfer -2 to the other side it turns to +2

|2x-1|=7 +2

2x-1 =9

transfer -1 to the other side it turns to +1

2x=10

Divide both sides by 2

2x /2 = 10/2

x= 5
