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( "\"z=2x\" and \"z=%283%2F2%29y\";\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x%2By%2Bz=1\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Three equations in three unknown variables. Solve any way you want.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "A method can be: Use the first equation for z and substitute into the other two equations.
\n" ); document.write( "\"2x=%283%2F2%29y\" and \"x%2By%2B2x=1\";
\n" ); document.write( "\"y=%282%2F3%292x\" and \"3x%2By=1\";
\n" ); document.write( "\"y=%284%2F3%29x\" and \"3x%2By=1\".
\n" ); document.write( "Take this formula for y and substitute into the other equation;
\n" ); document.write( "\"3x%2B%284%2F3%29x=1\"
\n" ); document.write( "solve for x,
\n" ); document.write( "\"9x%2F3%2B4x%2F3=1\"
\n" ); document.write( "\"13x%2F3=1\"
\n" ); document.write( "\"highlight%28x=3%2F13%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Going back to the original first two equations, you would use x to find z, and use z to find y.
\n" ); document.write( "
\n" );
