Mia weighs 30 kilo plus half the weight of Pia.
Pia weighs 4/7 of the weight of Mia
How much do they weigh together?

How much does Pia and Mia weigh separately?

Oops. Screwed up that post. Sorry.
30 +4/7 of 30=9+18+weight 18 + 57
You got a different answer than mine.
You should take 4/7 of (30 + half pia's weight)

Formula to use:
Mia = 30 Kg + 1/2 P
P=4/7 (30 + 1/2 P)
7P = 4 (30 + 1/2 P)
P=24......substitute into above equation for Mia in terms of P>>>
Mia= 42
