Would someone please check my work to see if I did it right ?
Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $27 monthly fee and charges an additional $0.13 for each minute of calls. The second plan has an $11 monthly fee and charges an additional $0.17 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?
27+0.13x=27.13x subtract 0.13x from both sides which is -27 11+0.17x=11.17x subtract 0.17 from both sides leaving you with 11 divide -27 by 11 =3.8

You set up the expressions right, but you're supposed to set them equal and keep the x's.
