Answer 1

Answer:

The answer to your question is:

Step-by-step explanation:

Equation                            12(c + 6) = 7

Step 1: 12c+6=7                   The mistake is that she forgot to multiply 12 by 6

Step 2: 12c=7+6                    She forgot to change the sign of 6

Step 3: 12c=13                      

Step 4: c=13÷2                      She must divide 13 by 12 noy by 2

Step 5: c=612                       She divide 13 incorrectly
