Question

AGES Robert’s father is 5 years older than 3 times

Robert’s age. Let Robert’s age be denoted by R and
let Robert’s father’s age be denoted by F. Write an
equation that relates Robert’s age and his father’s age.

Answer 1

F = 3R + 5

Explanation:

3 times Robert's (R) age is 3R and 5 more than this is 3R + 5

Father (F) is 5 years older than 3 times Robert's age , then

F = 3R + 5 ← equation relating their ages
