one number equals three times another number.the difference between the numbers is 10.find the numbers.\r
\n" ); document.write( "\n" ); document.write( "one number = x
\n" ); document.write( "another number = y\r
\n" ); document.write( "\n" ); document.write( "x=3y
\n" ); document.write( "x-y=10\r
\n" ); document.write( "\n" ); document.write( "substitute:
\n" ); document.write( "x-y=10 turns into
\n" ); document.write( "3y-y=10 (simplify)
\n" ); document.write( "2y=10 (divide by two)
\n" ); document.write( "y=5\r
\n" ); document.write( "\n" ); document.write( "put back into original equation:
\n" ); document.write( "x=3y
\n" ); document.write( "x=3(5)
\n" ); document.write( "x=15\r
\n" ); document.write( "\n" ); document.write( " x=15, y=5
\n" ); document.write( " \n" ); document.write( "
\n" );
