Present age of Justin=14
Present age of Sam=11
Step-by-step explanation:
Let the present age of Sam=x
Given that Justin is 3 years older than Sam
present age of Justin=x+3
Age of Sam 3 years ago=x-3
Age of Justin two years hence=x+3+2=x+5
given that after 2 years Justin's age will be twice that of Sam's age three years ago
therefore
[tex]x+5=2(x-3)x+5=2x-6\\5+6=2x-x=x\\11=x[/tex]
Present age of Sam=x=11
Present age of Justin=x+3=11+3=14
