x-.92x=24 How to solve on Prime? - SalivationArmy - 04-23-2016 07:47 AM
is there a name for this type of equation? x-.92x=24 and how do I make the prime solve this? I know the answer is x=300, but I cannot figure out how to make the prime solve an equation like this. RE: x-.92x=24 How to solve on Prime? - salvomic - 04-23-2016 08:03 AM

Hi SalivationArmy, that's an equation with one variable having no powers, it's called first-degree equation ;-) Just collect like terms, isolate the variable and get x by itself: x*(1-0.92)=24 --> 0.08*x=24 --> x=24/0.08=300, that's it ! A piece of cake for the Prime !!!!! Best, Aries :-) RE: x-.92x=24 How to solve on Prime? - DrD - 04-23-2016 09:53 AM
Another way, (assuming X is a real number): In the Apps Library, the Solve App can be useful in [HOME] mode for linear equations like your example. Remember to use upper case X for your variable when you enter your equation in the [Symb] view. Then go to the [Num] view and just press the [Solve] black soft-key, which will return 300 in the solve box for X. -Dale- |
