Answer by checkley77(12844) (Show Source): You can put this solution on YOUR website!
(X-3)/X=4/7 CROSS MULTIPLY
7(X-3)=4X
7X-21-4X=0
3X=21
X=21/3
X=7 ANSWER.
PROOF:
(7-3)/7=4/7
4/7=4/7
-----------------------------------
IF YOU MEAN X-(3/X)=4/7 THEN:
(X^2-3)/X=4/7 CROSS MULTIPLY
7(X^2-3)=4X
7X^2-21-4X=0
7X^2-4X-21=0
USING THE QUADRATIC EQUATION WE GET:
(2.04 & -1.47)
------------------------------------------------
IN THE FUTURE PLEASE MAKE BETTER USE OF THE ( ) AS YOU CAN SEE IT MAKES QUITE A DIFFERENCE HOW THESE TERMS ARE INTERPRETED.
