1380.0. "an easy one for you." by SMD72J::WOOD (Petey P. Eight) Fri Feb 01 1991 09:28

    This seems to be the right place to put this question, so, here goes.
    
    I am working on a program to do some special things for my car
    expenses.  What I need mathematically is to have the following formula
    figured out for "X".
    
    (A * B * X/C) + (D * X) = E
    
    Now find         X = ?
    
    I am not sure that if I try to figure out my answer would be correct.
    That is probably because I spent to my hours trying to figure out what
    a french math insructor was trying to say.
    
    thanx

1380.1	Perhaps not the right place, but	SUBURB::STRANGEWAYS	The brain's trussed	`Fri Feb 01 1991 09:42`	6
	X = E/( (A*B)/C + D ) [In English. Maybe it's different in French?] Andy.
1380.2		GUESS::DERAMO	Dan D'Eramo	`Fri Feb 01 1991 09:50`	7
	Or, the same thing, E X = ------- A*B --- + D C

	> X = E/( (AB)/C + D ) > > [In English. Maybe it's different in French?] Dunno bout French, but in Polish it's EABC/D+/ :-) Andrew.
1380.4	Thanks to all	SMD72J::WOOD	Petey P. Eight	`Fri Feb 01 1991 11:23`	6
	Thanks for the fast reply from everyone! By the way, what I meant by the french instructor was that his english was not the best and I could not always understand him. ...jay
1380.5	correction to .0	SMD72J::WOOD	Petey P. Eight	`Fri Feb 01 1991 13:45`	9
	ooooops (A * B * X/C) + (D * X) - F = E X = ? ...j
1380.6	Essentially the same.	CADSYS::COOPER	Topher Cooper	`Fri Feb 01 1991 14:58`	3
	Replace "E" by "E+F" in any of the previous replies. Topher
