sapphiremoon · Answer

@RomanceLanguages Are you allowed to combine digits to form double digit numbers? I think the way to go about finding the largest value of a variable is give it a small coefficient and a small constant and a large final value (like 2x + 1 = 9 is has a larger x value than 3x + 1 = 7) and vice versa for the smallest...

romancelanguages · Answer

yeah i thought it was that way

sapphiremoon · Answer

Well, maybe 2x + 1 = 98 would give you the largest value for x, etc.
