K. so, first off lets make julies weight be x and teds weight be 2x and mikes weight be 3x and all of them together weigh 210.

x+2x+3x=210. now lets solve.

so firsts off we combine like terms like this: 
(x+2x+3x)=210=
6x=210
Now we divide both sides by 6 (and the 6x will be crossed out)

and 210/6 is 35

now we know that julies weight is 35

and teds weight is 2x so 2*35=70 
so teds weight is 70

now mikes weight: so 3*35=105<-- mikes weight

Oh and i forgot one more thing.

so if we add all their weights itll add up to 210

105+70+35=210
