 y = 4x + 11\r\n" );
document.write( "3x - 2y = -7\r\n" );
document.write( "\r\n" );
document.write( "The first equation is already solved for y, so replace \r\n" );
document.write( "the y in the second equation by what y equals, namely,\r\n" );
document.write( "(4x+11)\r\n" );
document.write( "\r\n" );
document.write( "      3x - 2y = -7\r\n" );
document.write( "3x - 2(4x+11) = -7\r\n" );
document.write( " 3x - 8x - 22 = -7\r\n" );
document.write( "     -5x - 22 = -7\r\n" );
document.write( "          -5x = 15\r\n" );
document.write( "            x = -3\r\n" );
document.write( "\r\n" );
document.write( "Now to find y, replace x by -3 in the first equation:\r\n" );
document.write( "\r\n" );
document.write( "   3x - 2y = -7\r\n" );
document.write( "3(-3) - 2y = -7\r\n" );
document.write( "   -9 - 2y = -7\r\n" );
document.write( "       -2y = 2\r\n" );
document.write( "         y = -1\r\n" );
document.write( "\r\n" );
document.write( "So the solution is (x, y) = (-3, -1)\r\n" );
