3x + 2y = 235.000
Eliminasi:
2 = 4x + 2y = 280.000
1 = 3x + 2y = 235.000
Lalu dikurangi sehingga menjadi
x= 45.000
Jadi harga 1baju 45.000
2x + y = 140.000
2.45000 + y = 140.000
90.000 + y = 140.000
y = 140.000 - 90.000
y = 50.000
Jadi harga 1celana adalah 50.000
Harga 4 baju dan 5 celana adalah
4.45000 + 5.50000 =
180.000 + 250.000 = 430.000
