You can
put this solution on YOUR website! I am a 2-digit number.
Let t = your tens digit
Let u = your units digit
The sum of my digits is 6.
t + u = 6
My units digit is 2 times my tens digit.
u = 2t
So you have this system of equations:
t + u = 6
u = 2t
Substitute 2t for u in t + u = 6
t + 2t = 6
3t = 6
t = 2
u = 2t = 2(2) = 4
Who am I?
You are the number 24.
