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.

In CAS:
solve(x-.92x=24, x) -> 300

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 :-)

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.
