Question 858002: I am a 2-digit number. My digits total 5 and have a difference of 1. Who am I?
That is the question, need to understand how to work out? Is 2 digits 10? Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! x = first digit
y = second digit
x + y = 5
x - y = 1
these are 2 equations that need to be solved simultaneously.
add the 2 equations together and the y will cancel out and you will be left with 2x = 6
divide both sides of this by 2 and you get x = 3
this means that y has to be equal to 2 because.
3 + 2 = 5
3 - 2 = 1
your digits are 3 and 2.
