Algebra.Com's Answer #649575 by Edwin McCravy(20060)![]() ![]() You can put this solution on YOUR website! X is 5 years older than Y. X = Y+5Z is 6 years older than X. Z = X+6...the sum of their ages is 31... X+Y+Z = 31\r\n" ); document.write( "\r\n" ); document.write( "First substitute (Y+5) for X in Z = X+6\r\n" ); document.write( "and simplify.\r\n" ); document.write( "\r\n" ); document.write( "Then substitute (Y+5) for X and Z = (what you got)\r\n" ); document.write( "into X+Y+Z = 31 and solve for Y.\r\n" ); document.write( "\r\n" ); document.write( "Then substitute that value for Y in X = Y+5 to\r\n" ); document.write( "find X.\r\n" ); document.write( "\r\n" ); document.write( "Then substitute what you got for X in Z = X+6\r\n" ); document.write( "to find Z.\r\n" ); document.write( "\r\n" ); document.write( "I won't tell you the answers but one of them is\r\n" ); document.write( "twice as old as another of them.\r\n" ); document.write( "\r\n" ); document.write( "Edwin\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
