jumlah uang arif dan bima Rp 112.000 uang charles 5/8 uang bima sedangkan uang arif 3/4 uang bima

A + B = 112.000
C = 5/8B
A = 3/4B

A + B = 112.000 .................. Pers. 1
5/8B - C = 0 ......….…………… Pers. 2
A - 3/4B = 0 …………………….. Pers. 3

eliminasi A
A + B = 112.000 .................. Pers. 1
A - 3/4B = 0 …………………….. Pers. 3
maka
7/4B = 112.000
B = 112.000 x 4/7
B = 64.000 (uang bima)

A = 3/4B
A = 3/4 x 64.000
A = 48.000 (uang arif)

C = 5/8B
C = 5/8 x 64.000
C = 40.000 (uang charles)
