Algebra.Com's Answer #84561 by psbhowmick(878)![]() ![]() You can put this solution on YOUR website! Even nos. are of the form 2n where n = any non-zero integer. \n" ); document.write( "If the 1st no. is 2n then the second one is obviously 2(n+1).\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Their sum is: 2n + 2(n+1) = 126 \n" ); document.write( "4n + 2 = 126 \n" ); document.write( "4n = 126 - 2 \n" ); document.write( "4n = 124 \n" ); document.write( "n = 124/4 = 31\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So, the nos. are 2x31 and 2(31+1) i.e. 62 and 64 respectively. \n" ); document.write( " |
