y=-sin(x/15)*1000./((x-90).^2+(y-110).^2+60)+sin(x/30)*500./((x-55).^2+(y-55).^2+30)+80./(12+abs(x-15))+60./(12+abs(x-20))+80./(12+abs(x-25));

To improve readability I would suggest a line break after every term:
y=-sin(x/15)*1000./((x-90).^2+(y-110).^2+60) ...
+sin(x/30)*500./((x-55).^2+(y-55).^2+30) ...
+80./(12+abs(x-15)) ...
+60./(12+abs(x-20)) ...
+80./(12+abs(x-25));
