You can put this solution on YOUR website!
\"5x%2B10y=30\"
\n" ); document.write( "\"5x%2B3y=2\" At this point you need to subtract one equation from the other, not add them. When you do that you get:
\n" ); document.write( "\"7y=28\"
\n" ); document.write( "\"y=4\"\r
\n" ); document.write( "\n" ); document.write( "Substituting in for the first equation:
\n" ); document.write( "\"x%2B2y=6\"
\n" ); document.write( "\"x%2B2y=6\"
\n" ); document.write( "\"x%2B2%284%29=6\"
\n" ); document.write( "\"x=-2\"
\n" ); document.write( "
\n" );
