document.write( "Let x be the number of goats; then the number of chicken is (35-x).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now we write equation counting the legs\r\n" );
document.write( "\r\n" );
document.write( "    4x + 2*(35-x) = 110.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Simplify and find x\r\n" );
document.write( "\r\n" );
document.write( "    4x + 70 - 2x = 110\r\n" );
document.write( "\r\n" );
document.write( "         2x      = 110 - 70\r\n" );
document.write( "\r\n" );
document.write( "         2x      =    40\r\n" );
document.write( "\r\n" );
document.write( "          x      =    40/2 = 20.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  20 goats, and the rest  35 - 20 = 15 are chicken.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.   Count the legs:  20*4 + 15*2 = 80 + 30 = 110.    !  Correct !\r\n" );
