Question

FIRST ANSWER GET A MEDAL
The digits of a two-digit number sum to 8. When the digits are reversed, the resulting number is 18 less than the original number. What is the original number?

Answer 1

I will try my hardest to help you! :)

Answer 2

Let x = the 10's digit
Let y = the units
:
10x + y = the original two digit number
:
The sum of the digits of a two-digit number is 14.
x + y = 14
:
"If the digits are reversed, the number is 18 less than the original number."
Rev no. = orig no. - 18
10y + x = 10x + y - 18
10y - y = 10x - x - 18
9y = 9x - 18
simplify, divide by 9
y = x - 2

Answer 3

Answer 4

You know...if you're going to copy and paste a way to solve a problem, least you could do is change it to match the question.

Answer 5

so in other words the answer would be -2

Answer 13

Okei, so let me explain how you could find the answer:

You have a number, a. This number is made up of two digits, we'll use x and y. According to the problem, x + y = 8. So you need to find two numbers that, when added, give you 8. It's easier to list out the numbers that can give you this.

1 7
2 6
3 5
4 4
5 3
6 2
7 1

All these, when added with their corresponding number, equal to 8 and, when put together, they give you a two-digit number. So now, looking at the list, each set of numbers have a reversed side to it. With that, you need to see which one, when subtracted with it's reverse, gives you 18.

17 reverses to 71... 17-71=?
26 reverses to 62... 26-62=?
35 reverses to 52... 35-53=?
44 reverses to 44... 44-44=?
53 reverses to 35... 53-35=?
62 reverses to 26...62-26=?
71 reverses to 17... 71-17=?

So now, try and see if you can work this out.
