animate object to defined location

animate object to defined location

hi all,
this code moves otherobject 40 less, 100 more
but I want to specific location like to top:'40px' and left:'100px'. How can I do this?

$("div#myobject").on("click",function(){
    $("div#otherobject").animate({
    top: '-=40',
    left:'+=100'
    }, 1500, function() {
    });
});
