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.
