Sebut ajaData 1 = a
Data 2 = b
Rata Rata a dan b = 171cm
a-b = 6cm
Tinggi badan nya?
Rata Rata = a+b/2
171 = a+b/2
a+b = 342 cm
Metode eliminasi
a+b = 342
a-b = 6
___________(+)
2a = 348
a= 174 cm
a-b=6
174-b=6
168=b
Tinggi A = 174 cm
Tinggi B = 168 cm
Semoga membantu ^^

misal data 1=a
misal data 2=b
misal b>a
b-a=6cm
b=6cm+a
171cm=(a+b)/2
171cm×2=a+(6cm+a)
342cm=2a+6cm
a=(342cm-6cm)/2
a=336cm/2
a=168cm
b=168cm+a
=168cm+6cm
=174cm
Jadi dua data tersebut adalah 174cm dan 168cm
