Answer:

Her mistake was in step 1

Step-by-step explanation:

Given the expression solved by Alanna

4c = 12

To get c, we will divide both sides of the equation by 4:

4c/4 = 12/4

c = 12/4

c = 3

Alanna made mistake in step 1 where she divided multiplied the right hand side of the equation by 4 instead of dividing by 4
