Question 7 (10 points): Miranda is a 10th grade student who is very good in problem solving. In fact, she just completed an advanced algebra class and received a grade of A+. Miranda has five sisters, Cathy, Stella, Eva, Lucinda, and Dorothea. Miranda made up a problem involving the ages of the six girls and dared Cathy to solve it. Miranda said, "The sum of our ages is five times my age, (by 'age' throughout this problem we mean "age in years.) when Stella is three times my present age, the sum of my age and Dorothea's will be equal to the sum of the present ages of the five of us; Eva's age will be three times her present age; and Lucinda's age will be twice Stella's present age, plus one year. How old are Stella and Miranda?" "Well, Miranda, could you tell me one more thing, please?" "Sure", said Miranda, "my age is an odd number".
