baju = B
2s + 3b = 600.000
4s + b = 700.000
======================================== (pakai cara eliminasi)
4s + 6b = 1200.000
4s + b = 700.000
--------------------------------- (dikurangi)
5b = 500.000
b = 100.000
berarti harga 1 baju adalah 100.000

2s + 3b = 600000
2s + 3(100000) = 600000
2s + 300000 = 600.000
2s = 600000 - 300000
2s = 300000
s = 150000
berarti 1 sepatu harganya 150.000
