.
69 = 23*3 = 69*1,  


and Shiela is younger. 


It implies that one of two cases is in place:


Case a): Shiela age 7 years ago was 3, so she is 10 years old now.


Case b): Shiela age 7 years ago was 1, so she is  8 years old now.


From this point you can complete the solution on his own, by excluding one of the two cases, based on other conditions.
