Answer:
64
Step-by-step explanation:
Let the tens digit be x and units digit be y. We can write the number we are finding as 10x + y. We also know that x + y = 10 and 10x + y - (reversed number) = 10x + y - (10y + x) = 9x - 9y = 18.
Dividing by 9 on both sides, we get:
x - y = 2
Using the equations x + y = 10 and x - y = 2, we find that x = 6 and y = 4. So the number is 64.
I hope this helps! :)
