goodyhi11 Posted January 24, 2005 Share Posted January 24, 2005 If ex - fy= gx + hy find ratio of x to y Answer is highly appreciated. Link to comment Share on other sites More sharing options...
Dave Posted January 24, 2005 Share Posted January 24, 2005 Just re-arrange the equation to give x on one side: x(e-g) = y(h+f) (does this answer the question, or am I being silly? I haven't done this for a while) Link to comment Share on other sites More sharing options...
ed84c Posted January 24, 2005 Share Posted January 24, 2005 is finding aswers for you hw all you ever use this site for? ex- fy= gx + hy ex-gx= Fy + hy ex-gx= (f+h)y (e-g)x=(f+h)y x=(f+h)y/(e-g) there for for every x there is (f+h)y/(e-g) hope that helps Link to comment Share on other sites More sharing options...
Dave Posted January 24, 2005 Share Posted January 24, 2005 ex-gx= Fy + hy ex-gx= fhy Er, nope. fy + hy does not equal fhy. Post #1 gives the correct factorisation. Link to comment Share on other sites More sharing options...

goodyhi11 Posted January 24, 2005 Author Share Posted January 24, 2005 thanks dave i believe your first post was right. Thanks to you also ed84c, your first few steps was right, but i think you are a little off at last few steps. Link to comment Share on other sites More sharing options...
Dave Posted January 24, 2005 Share Posted January 24, 2005 Well, he's just saying that the ratio is 1 : (f+h)/(e-g) which is equivalent to the ratio (e-g) : (f+h). Link to comment Share on other sites More sharing options...
