Since we know one number is one third of another number, we can say:
\n" ); document.write( "x = one number
\n" ); document.write( "1/3x = the other number
\n" ); document.write( "Now, we also know their sum equals the larger # minus 1, so here's your equation:
\n" ); document.write( "\"x%2B%281%2F3%29x=x-1\"
\n" ); document.write( "Now solve for x to find the first number:
\n" ); document.write( "\"%281%2F3%29x=x-1-x\"
\n" ); document.write( "\"%281%2F3%29x=-1\" ...multiply by 3 on both sides...
\n" ); document.write( "\"x=-3\" This is your first number.
\n" ); document.write( "Now calculate your second number by pluging this value in
\n" ); document.write( "\"%281%2F3%29x\"
\n" ); document.write( "\"%281%2F3%29-3\"
\n" ); document.write( "\"-1\" This is your second number.
\n" ); document.write( ".
\n" ); document.write( "Proof:
\n" ); document.write( "Plug in these values in the original equation. Both sides of the eqn must equal to each other.
\n" ); document.write( "\"x%2B%281%2F3%29x=x-1\" ...by substitution...
\n" ); document.write( "\"-3%2B%28-1%29=%28-3%29-1\"
\n" ); document.write( "\"-4=-4\"
\n" ); document.write( "Done!
\n" ); document.write( "
\n" );
