Now the problem tells us that 98 years ago, your were 2 years old and your brother was (1/2)*2=1 year old
So our equation to solve is:

x=99 years old----your brother's age
Answer:
99 years old.

When you were two, your brother was half your age, that is one year old. So when you're 100 years old, your brother will be 1 year less than you. Therefore he will be 99 years old.
