Question

roberts father is 5 years older than 3 times roberts age. let roberts age be denoted by R and let rogers father's age be denoted by F.

Answer 1

The equation that represents this problem is 3r+5=f

Answer 2

F = 3R + 5

Explanation:

Let the Roberts age be R

Also, let the Roberts father's age is F

It is given that Roberts father is 5 years older than 3 times Robert's age which means that Roberts Father's age is 5 years more than 3 times the age of Roberts

∴ Roberts Father's age is: 3 times of Robert age + 5 years

⇒ F = 3 × R + 5

⇒ F = 3R + 5

which is Roberts Father's age.
