Otieno is k years old.He is 5 years older than kidole what will be their age fours to come

EleoNora [17]

Answer:

Otieno's age in 4 years: $k+4$

Kidole's age in 4 years: $k-1$

Step-by-step explanation:

$k$ = Otieno's age

$k-5$ = Kidole's age

Their ages will increase by 4 years when 4 years pass.

$k+4$ = Otieno's age in 4 years

$k-5+4$ = Kidole's age in 4 years

$k-1$ = Kidole's age in 4 years (after simplifying the expression)
