Armans age : x
Aregs age: y
X = 5y
(15 - 12) = y. They said narek is 12 years older than areg so you deduct 12 years from nareks age which is 15.
So therefore y = 3. So Areg is 3 years old.
Since we know that y = 3
X = 5(3)
X = 15
So therefore Arman is 15 years and Areg is 3 years.

2x + 5x + 4 = 25
7x + 4 = 25
7x +4 (-4) = 25 (-4)
7x = 21
7x/7 = 21/7
x = 3
26 = 3b - 2 - 7b
26 = 4b - 2
26 + 2 = 4b - 2 (+2)
28/4 = 4b/4
b = 7
