Step-by-step explanation:
Let there be two variables: t and o where t is for ten digit and o is for one digit:
So we have two equations:
t = 2o (1)
t+o = 12 (2)
Subtract (2) from (1) and we get o = 12-2o
Now solve for o:
3o = 12
o = 4
Now plug in (1) or (2) and we have t = 8
Therefore our number is 10t + o = 84
