- L = 6
P = 6 + L

(64L + 72P) / (L +P) = 68,8

64L + 72P = 68,8 (L+P)
64L + 72P = 68,8L + 68,8P
72P - 68,8P = 68,8L - 64L
3,2P = 4,8L
2P = 3L

2(6+L) = 3L
12 + 2L = 3L
12 = L
Laki-laki = 12
Perempuan = 6 +L = 6+12 = 18
Jumlah siswa = 12 + 18 = 30 Orang.

Yg mau saya tnyakan. 2P=3L, dpt drimana ya?
Tlg bantu jawabya:)
