tolong dijawab pakai cara

pakai cara eliminasi:

2b + 4p = 18000      |
3b + 2p = 23000      | x 2

2b + 4p = 18000
6b + 4p = 46000
----------------------  -
-4b = -28000
b = 7000

2.7000 + 4p = 18000
4p = 4000
p = 1000

5b+2p = ?
5.7000 + 2.1000 = ?
35000 + 2000 = 37000 (C)

2b+4p=18000 I 1 I 2b+4p=18000
3b+2p=23000 I 2 I 6b+4p=46000
____________ -
-4b= -28000
b=7000
2b+4p=18000
2(7000)+4p=18000
4p=18000-14000
4p=4000
p=1000

5b+2p=5(7000)+2(1000)
=35000+2000
=37000 (C)
