Question

Pete is 14 and his grandfather is 54. How many years
ago was his grandfather 6 times as old as Pete?

Answer 1

Answer:

6 years ago

Step-by-step explanation:

$6(14-x)=54-x\\84-6x=54-x\\30-6x=-x\\30=5x\\6=x$

So, Pete's grandfather was 6 times as old as Pete 6 years ago. This means that when Pete was 8 years old, his grandfather was 48 years old.
