Kadesha is simplifying the expression below. Negative (x minus 3) minus 2 (x minus 1)

She lists the steps that she uses to simplify the expression as follows:

Step 1: Distribute –1 through (x minus 3), and distribute –2 through (x minus 1).
Step 2: Rewrite the expression as Negative x minus 3 minus 2 x minus 2.
Step 3: Combine –x and –2x, and combine –3 and –2.
Step 4: The simplified expression is Negative 3 x minus 5.

In which step did Kadesha make the first error?
She made the first error in Step 1 because only –2 should be distributed through the parentheses.
She made the first error in Step 2 because Step 2 should be Negative x + 3 minus 2 x + 2.
She made the first error in Step 3 because –x and –2x cannot be combined.
She made the first error in Step 4 because the simplified expression is Negative x minus 5.
