Hi from quebec city, first post and i speak french so i'm not good with english math expresisons...anyway

ok i managed to get an equation, but i can't simplify it.

can you solve this please.

x*((165/(x/65000))+.05) - x = 0

Thanks alot

rapha i hope you are still there, i made a mistake, my equation is

x*((165/(x/65000))+.05) = y

i need to find that y but i don't know how because it's in relation with my x. related to this equation, the final equation i need to solve is this:

20 475 000 + x((165/(x/65000))+.05) = x

i hope you understand me ;) - November 10th 2008, 09:26 PMRapha
No, i do not, sorry

i need to find that y

x*((165/(x/65000))+.05) = 0.05*x + [165x /( x /(65000)) ]

= 0.05x + [165 / (1/65000)]

= 0.05x + 165*65000 = y

its a linear function

20 475 000 + x((165/(x/65000))+.05) = x

I dont know

Anyway, you know x((165/(x/65000))+.05) = 0.05x + 165*65000

=> 20 475 000 + 0.05x + 165*65000 = x

=> 20 475 000 + 0.05x-x + 165*65000 = 0

...

=> x = ???
