Question

5) My younger brother's age today is 3 times what it will be 3 years from now minus 3
times what his age was 3 years ago. If my brother is 5 years younger than me, what
is my present age?​

Answer 1

Answer:

Let the brother's age be x

then,

x = 3(x+3)-3(x-3)

or = 3x+9-3x+9

or = 18

x = 18

your age = x + 5

Your age = 23
