X + y = 180x = 180 - y
20.000x + 40.000y = 4.200.000
20.000(180 - y) + 40.000y = 4.200.000(sama sama dibagi 10.000, biar lebih gampang menghitungnya)
2(180 - y) + 4y = 420
360 - 2y + 4y = 420
2y = 420 - 360
2y = 60
y = 30
x = 180 - 30 = 150
150( 20.000) + 30(40.000) =
3000.000 + 1.200.000 = 4.200.000
