anonymous · Answer

im confused

anonymous · Answer

oh, it no choices, you suppose to solve it

anonymous · Answer

ok hol up o.O

anonymous · Answer

you need to make an equation 
so lets say Da Eum is x yeas old
and her sister is x-5

anonymous · Answer

therefore 
x+(x-5)=57 
would be used to solve option A

anonymous · Answer

I don't get it, isn't it $$x-5\ge57$$

anonymous · Answer

it cannot just be only x-5
because that is the age of Da Eum younger sister

anonymous · Answer

Da Eum has to be x itself
with her sister 5 years younger (x-5)

anonymous · Answer

and the question says at most 57 meaning it cannot be >57

anonymous · Answer

$$\le $$

anonymous · Answer

?

anonymous · Answer

So it x+(x-5)$$\le 57$$

anonymous · Answer

yeah that is better$$x+(x-5)\le57$$

anonymous · Answer

so solve for x to find individual ages
