Question

Jawabannya adalah....

Answer 1

Misal
anas = a
bella = b
chesi = c

diketahui
a = 5000 + 2b
c - b = 12.000 --> c = 12.000 + b
a + b + c = 65.000
a+b = ???

jawab
a + b + c = 65.000
(5000 + 2b) + b + (12.000 + b) = 65000
17000 + 4b = 65000
4b = 65000-17000
4b = 48000
b=12000 .............uang bella rp 12000

a = 5000 + 2b = 5000 + 2(12000) = 29000.......... uang anas rp 29000

maka uang anas dan Bella = 12000 + 29000 = 41000
