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 four-digit number between 12 and 13 has an odd number in the hundredts place and an even number in the tenths
