Demola is two years older than Deji and Tobi is half of Demolas age.
The sum of their ages is 23. How old is deji?
~~~~~~~~~~~~~~
Demola age = x years.
Deji age = (x-2) years.
Tobi age = . years.
Write equation for the combined age as you read the problem
x + (x-2) + = 23.
Multiply both sides by 2 to rid of denominators; then simplify and find x
2x + 2(x-2) + x = 2*23
2x + 2x - 4 + x = 46
5x = 46 + 4 = 50
x = 50/5 = 10.
ANSWER. Demola is 10 years old.

Since Deji's age is required, we LET Deji's age be D
Then Demola's is: D + 2, and Tobi's is:
With their ages summing to 23, we get:
4D + D + 2 = 42 ------ Multiplying by LCD, 2
5D = 40
Deji's age, or
You're welcome, Tutor @Ikleyn, although I wasn't trying to correct you. If the "student" paid attention to your answer, he/she
would've noticed that you gave Demola's age, and all he/she had to do was subtract 2 from that age to get Deji's age. That's all!
