Algebra.Com's Answer #2643 by longjonsilver(2297)![]() ![]() You can put this solution on YOUR website! Let a= Alex's age now \n" ); document.write( "Ley g = George's age now \n" ); document.write( "Let the other 3 be w, x, and y --> or rather let w+x be z, since we will let y be the person who has the birthday.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So, yza = 2450 --> eqn 1\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "y+z = 2g --> eqn 2\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Let y be the person you talked to --> y = a-5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So, we have 4 things we do not know: a, g, y and z but only 3 equations, so I do not believe you can find out anything here. You need more information, relating the ages.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "jon. \n" ); document.write( " \n" ); document.write( " |
