I am a 2-digit even number. I am less than. 60. Add my digits to get 12. Subtract one of my digits from the other to get 4. What number am i?
48
x - y = 4
Add y to both sides.
x = y + 4
x + y = 12
Substitute y+4 for x in last equation and solve for y. Insert that value into the first equation and solve for x.
I DON'T WANT x+y=4!
To solve this problem, we'll need to break it down into steps.
Step 1: Determine the possible values for the tens digit.
Since the number is less than 60 and even, the possible values for the tens digit are 2, 4, and 6.
Step 2: Determine the possible values for the units digit.
We know that the sum of the digits is 12, so one of the digits must be greater than or equal to 6. From this, we can conclude that the possible values for the units digit are 6 and 8.
Step 3: Determine the difference between the digits.
Subtracting one digit from the other gives us a difference of 4. From this, we can conclude that the tens digit must be 4 and the ones digit 8.
Therefore, the number is 48.
