If the tens digit of a twodigit number is subtracted from the units digit, the difference is 8. The number with the digits reversed is 10 more than nine times the units digit of the original number. Find the number.

Hint:
There are only two digits that can make a difference of 8, namely 9 and 1.
Can you take it from here? 
can you set up the two equations for me?

I am a 2 digit number. The sum of my digits is 12 . My tens digit is 4 more than my ones digit. What number am I ?

X + y = 12
X  y = 4
12 + 4 = 16
16: 2 = 8
8 + 4 = 12
8  4 = 4
Tha number is 84 
1000000

a fourdigit number between 12 and 13 has an odd number in the hundredts place and an even number in the tenths
