Question

What is the value of x in |2x - 3|=1?
Write and solve equations for the two possibilities:

Answer 1

Answer: x = 1, 2

Explanation:

|2x-3|=1

2x-3 = 1, 2x = 4, x = 2

-(2x-3)=1, 2x-3 = -1, 2x = 2, x = 1

Answer 2

x=1 or x=2

Explanation:

|2x - 3|=1

2x-3=1

2x=4

x=2

2x-3=-1

2x=2

x=1

x=1 or x=2
