???

KjSaif (kjsaif):

You were not here so i tagged you

OpenStudy (samantha2234):

Ok....

KjSaif (kjsaif):

ok in order to find it first you you write an equation

KjSaif (kjsaif):

you know that Her sister times 2 = Kim

KjSaif (kjsaif):

So Lets make the variables....

OpenStudy (simontheengineer):

36 divide by 3 is 12 and thus one is 12 and the other 24. 1 x 12 is 12 2 x 12 is 24 1 + 2 is 3 12 + 24 is 36

KjSaif (kjsaif):

S=Sister K=Kim

KjSaif (kjsaif):

Sx2=K

OpenStudy (samantha2234):

Is that all I had to do???

KjSaif (kjsaif):

no one more part

OpenStudy (samantha2234):

oh :P

KjSaif (kjsaif):

12 x 2 = 24

KjSaif (kjsaif):

24 + 12 = 36 Which was the answer

OpenStudy (leenathan):

*hands kj medal*

KjSaif (kjsaif):

so S x 2 = K Is 12 x 2 = 24

KjSaif (kjsaif):

That's your answer :)

OpenStudy (samantha2234):

KjSaif (kjsaif):
