Answer:
Age of younger brother is 4 years..
And age if elder brother is 14 years.
Step-by-step explanation:
Let us denote 'x' as the age of smaller brother,
then, the age of younger brother will be x+10 years.
x+x+10 = 18
2x+10 = 18
2x = 18-10
2x = 8
x = 8/2
x = 4
Age of younger brother is 4 years.
Age of elder brother = x + 10
= 4 + 10
= 14 years.
