Suppose i have a two -digit number.
00:02
First digit is x, second digit is y.
00:04
The sum of the digits, sum, add them together, is equals 14.
00:10
Okay, so i know that.
00:13
Then twice the 10's digit, the 10th digit is x.
00:18
So twice x exceeds the units digit by 1.
00:24
So it is greater than exceeds is greater than the unit's digit by 1.
00:31
Okay.
00:33
Find that number.
00:34
Okay.
00:35
So the sum of the digits is 14 and twice the first digit exceeds or maybe another way to say exceeds equals is greater than the unit's digit plus one.
00:51
Okay.
00:52
So what is this number going to be? let's say 2x equals y plus one...
