Josefina stopped at Step 3 because she wanted to isolate \(2x\) to solve for \(x\), but she made a mistake in step 1 by not properly handling the absolute value.
Josefina started to solve for x in the equation
3.5 = 1.9 - 0.8|2x - 0.6 | using the steps below:
1. 3.5 = 1.9 - 0.8 (2x - 0.6 )
2. 1.6 = -0.8(2x - 0.6 )
3. -2 =( 2x - 0.6 )
Why did Josefina stop at Step 3? And a she
