Answer:
60
Step-by-step explanation:
Let's consider 2-digit number 'xy'. We can reperesent it as 10*x + y, where x - tens digit, and y is units digit.
Task says, that tens exceeds unit's digit by 6, that means y = x - 6.
Now we can write equation:
10*x + (x-6) = 10* (x + (x-6))
10x + x - 6 = 10*(2x - 6)
11x - 6 = 20x - 60
11x - 20x = -60 + 6
-9x = -54
x = -54 / -9
x = 6, they y = 0
