Question

Josefina started to solve for x in the equation

3.5 = 1.9 – 0.8|2x – 0.6| using the steps below:
3.5 = 1.9 – 0.8|2x – 0.6|
1.6 = –0.8|2x – 0.6|
–2 = |2x – 0.6|
Why did Josefina stop at Step 3?

Answer 1

`3.5 = 1.9-0.8|2x- 0.6|`

`\text{using the steps below:}`

`3.5 = 1.9-0.8|2x-0.6|`

`1.6 = -0.8|2x-0.6|`

`-2 = |2x-0.6|`
