You can put this solution on YOUR website!
y = 1
\n" ); document.write( "2x + y = -15
\n" ); document.write( "2x + 1 = -15
\n" ); document.write( "2x = -15 - 1
\n" ); document.write( "2x = -16
\n" ); document.write( "x = -16/2 = -8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, the missing coordinate is x = -8
\n" ); document.write( "
\n" );
