Damon is 7 years older than his brother Mark. The sum of Damon and marks age is 29

Damon is 18, Damon's brother is 11 years old.

Step-by-step explanation:

So, the total age of them both is 29. Damon is 7 years older, so we use 29-7=22. Now, 22 is Damon's brother's age times 2, so we use 22/2=11. 11 is Damon's age is 11+7=18, and His brothers age is 11.

daman's age = (7+x)

let his brother's age be 'x'

according to the question,

(7+x) + x =29

7+x+x = 29

2x = 29 - 7

2x = 22

x = 22÷2

x = 11 = age of daman's brother

age of daman = 7+11 = 18
