Shelly incorectly solves the equation 12(c+6)=7. her work is shown. select all the steps that show an error based on the equation in the previous step. step 1: 12c+6=7 step 2: 12c=7+6 step 3: 12c=13 step 4: c=13÷2 step 5: c=612

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

answer: x=3 and y=4
