Algebra.Com's Answer #482019 by josgarithmetic(39617)![]() ![]() ![]() You can put this solution on YOUR website! Focus on the fractions. You are dividing whole 1 quantity of the \"rs\". \r \n" ); document.write( "\n" ); document.write( "x for youngest \n" ); document.write( "y for middle aged \n" ); document.write( "z for eldest\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Three equations in three unknown variables.
