x+y+3=0
\n" ); document.write( " 3x-2y+4=0\r
\n" ); document.write( "\n" ); document.write( " x + y = -3
\n" ); document.write( " 3x - 2y = -4\r
\n" ); document.write( "\n" ); document.write( "multiply the top equation by 2
\n" ); document.write( " 2x + 2y = -6
\n" ); document.write( " 3x - 2y = -4 add these together\r
\n" ); document.write( "\n" ); document.write( " 5x = -10
\n" ); document.write( " x = -2
\n" ); document.write( "Now substitute in
\n" ); document.write( " x + y = -3
\n" ); document.write( " -2 + y = -3
\n" ); document.write( "add 2 to each side
\n" ); document.write( " y = -1
\n" ); document.write( "So x = -2 and y = -1
\n" ); document.write( " \n" ); document.write( "
\n" );
