Since I WAY messed up last time, I'm retyping it:
In a two-digit number, the units digit is one less than twice the tens digit. If the digits are reversed, the new number is 20 less than twice the original number.
What's the original number? I'm working with substitution equations. So I need to have two equations and combine them. Could you also please show your work so that I can really understand it? Thanks everyone in advance. ^_^
