You can put this solution on YOUR website!
$\"2y%2Bx=9\"$ Start with the second equation.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"2y%2B2-y=9\"$ Plug in $\"x=2-y\"$ . In other words, replace each \"x\" with 2-y.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"y%2B2=9\"$ Combine like terms on the left side.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"y=9-2\"$ Subtract $\"2\"$ from both sides.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"y=7\"$ Combine like terms on the right side.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "----------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x=2-y\"$ Go back to the first equation\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x=2-7\"$ Plug in $\"y=7\"$ \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x=-5\"$ Subtract\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "=========================================\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer:\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the solutions are $\"x=-5\"$ and $\"y=7\"$ which form the ordered pair (-5,7) \n" ); document.write( "

\n" );
