Puzzle: I am less than ten years old. My brother is four times older than me. In ten years, he will be twice as old as me. How old am I and how old is my brother?

x=age
your age:x+10
Brother’s age: 4x+10
Equation: 4x+10=2(x+10)
Kinda solved equation: 4x+10=2x+20
Line up similar terms+switch operation:4x-2x=20-10
Whole equation solved:2x=10
Simplified version: 2x/2 10/2= x=5
Brother’s age solved: 4x‎ = 20

Your age:5
Brother’s age:20
