Set up a small system of equations:\r
\n" ); document.write( "\n" ); document.write( "\"x-y=8\"------>the difference between them is 7
\n" ); document.write( "\"x-2y=-7\"----->the larger is 7 less than twice the smaller.\r
\n" ); document.write( "\n" ); document.write( "Now solve the first for x and sub into the second:\r
\n" ); document.write( "\n" ); document.write( "\"%288%2By%29-2y=-7\"\r
\n" ); document.write( "\n" ); document.write( "\"8-y=-7\"\r
\n" ); document.write( "\n" ); document.write( "\"y=15\"\r
\n" ); document.write( "\n" ); document.write( "Therefore, x=23\r
\n" ); document.write( "\n" ); document.write( "The numbers are 15 and 23.\r
\n" ); document.write( "\n" ); document.write( "Check it out. The difference is 8: 23-15=8, CHECK.\r
\n" ); document.write( "\n" ); document.write( "The larger is 7 less than twice the smaller: 2(15)-7=23, CHECK.\r
\n" ); document.write( "\n" ); document.write( "See?. \r
