Answer:
23
Step-by-step explanation:
Please refer to the image given.
Let x be my present age, since my brother is 5 years younger than me, then his present age will be x - 5.
His age 3 years ago will be x - 8 and his age 3 years from now will be x - 2.
Then, the equation will be: (x - 5) = 3(x - 2) - 3(x - 8)
x - 5 = 3x - 6 - (3x - 24)
x - 5 = 3x - 6 - 3x + 24
x - 5 = 18
x = 23 years old
