nvme Posted June 3, 2004 Share Posted June 3, 2004 cross multiply then then add like terms, then get the one term you want on one side.. if possible Link to comment Share on other sites More sharing options...
FiREFLi Posted June 3, 2004 Share Posted June 3, 2004 Both sides of the bottom one have same denominator, simplify numerator then hopefully some stuff in the numerator might cancel with the denominator. :) Link to comment Share on other sites More sharing options...
nvme Posted June 3, 2004 Share Posted June 3, 2004 for the top one youshould be able to drop the denominator by multiplying both sides by x^2 - y^2. also.. what are the signs in the numerator between the x^2's and x's, etc? Link to comment Share on other sites More sharing options...
neowin_hipster Posted June 3, 2004 Share Posted June 3, 2004 Two equations and two unknowns. The rank appears to be 2. Now what does the bottom equation equal? Link to comment Share on other sites More sharing options...
atomicski Posted June 4, 2004 Share Posted June 4, 2004 i'd say first factor everything out..then see what cancels with the numerator and denomenator. Like the x^2 - y^2 would be (x-y)(x+y) and so on Link to comment Share on other sites More sharing options...
