Algebra.Com's Answer #464161 by stanbon(75887) ![]() You can put this solution on YOUR website! The sum of the reciprocals of 2 consecutive odd integers is 16/63. Find the numbers. \n" ); document.write( "I was thinking that the equation was 1/x + 1/x+2= 16/63 \n" ); document.write( "---- \n" ); document.write( "1st odd number: x-1 \n" ); document.write( "2nd odd number: x+1 \n" ); document.write( "----- \n" ); document.write( "1/(x-1) + 1/(x+1) = 16/63 \n" ); document.write( "------ \n" ); document.write( "Multiply thru by 63(x-1)(x+1) to get: \n" ); document.write( "63(x+1) + 63(x-1) = 16(x^2-1) \n" ); document.write( "------------------------------------ \n" ); document.write( "126x = 16x^2 - 16 \n" ); document.write( "16x^2 - 126x - 16 = 0 \n" ); document.write( "---- \n" ); document.write( "8x^2 - 63x - 8 = 0 \n" ); document.write( "(x-8)(8x+1) = 0 \n" ); document.write( "---- \n" ); document.write( "Whole number solution: \n" ); document.write( "x = 8 \n" ); document.write( "==== \n" ); document.write( "1st odd number: 2x-1 = 15 \n" ); document.write( "2nd odd number: 2x+1 = 17 \n" ); document.write( "============================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
