MY NAME IS YVETTE I AM A JUNIOR IN HIGHSCHOOL i take an algebra course in school and i have a problem for you  "Bobs dad is 27 yrs older then Bob. The sum of their ages 5 yrs ago was 45 yrs. How old is Bob now?" thank you for your time Hi Yvette Suppose that Bob's age is b, then Bob's dad's age is b + 27. Five years ago Bob's age was b  5 and Bob's Dad's age was b + 27  5 = b+ 22. Hence b  5 + b+ 22 = 55.
Cheers
