2m-n = 6
\n" ); document.write( "-n = 6-2m
\n" ); document.write( "n = 2m-6\r
\n" ); document.write( "\n" ); document.write( "m+2p = 4
\n" ); document.write( "m = 4-2p\r
\n" ); document.write( "\n" ); document.write( "3p-n = 5
\n" ); document.write( "recall n = 2m-6 from above
\n" ); document.write( "therefore equation becomes
\n" ); document.write( "3p-(2m-6) = 5
\n" ); document.write( "3p-2m+6 = 5
\n" ); document.write( "3p-2m = 5-6
\n" ); document.write( "3p-2m = -1\r
\n" ); document.write( "\n" ); document.write( "from above m = 4-2p
\n" ); document.write( "substitute this into equation.
\n" ); document.write( "3p-2(4-2p) = -1
\n" ); document.write( "3p-8+4p = -1
\n" ); document.write( "7p = 7
\n" ); document.write( "p = 1\r
\n" ); document.write( "\n" ); document.write( "recall from above m = 4-2p
\n" ); document.write( "therefore
\n" ); document.write( "m = 4-2(1) = 2\r
\n" ); document.write( "\n" ); document.write( "from above n = 2m-6
\n" ); document.write( "n = 2(2)-6
\n" ); document.write( "n = -2\r
\n" ); document.write( "\n" ); document.write( "So in summary:
\n" ); document.write( "n = -2
\n" ); document.write( "m = 2
\n" ); document.write( "p = 1
\n" ); document.write( " \n" ); document.write( "
\n" );
