Answer:
Simplifying by collecting like terms
Step-by-step explanation:
Given

The missing step
The missing step is at step 2.
At step 1, we have:
[tex]\frac{1}{2} - 2x +1 = -\frac{13}{2}[/tex]
At step 2, we have:
[tex]\frac{3}{2} - 2x= -\frac{13}{2}[/tex]
What she did at step 2, is that:
She collected like terms; 1 and [tex]\frac{1}{2}[/tex]
Then she simplified the like terms: [tex]1 + \frac{1}{2} =\frac{3}{2}[/tex]
Hence (a) is correct
