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?

Josefina stopped at Step 3 because at that point, the equation simplifies to |2x - 0.6| = -2. It is not possible for the absolute value of a number to be negative, so the equation has no solution.
