tolong ini cara gimana sekarang di kumpulin

MAPEL = MATEMATIKA
KELAS = 8
BAB = SPLDV

motor = x
mobil = y

eliminasi nilai x
x + y = 60 |×2
2x + 4y = 160 |×1

2x + 2y = 120
2x + 4y = 160
___________-
-2y = -40
y = -40/-2
y = 20

subtitusi nilai y
x + y = 60
x + 20 = 60
x = 60 - 20
x = 40

banyak motor = 40
banyak mobil = 20

harga parkir mobil = 5000
total = 5000 × 20
total = 100.000

harga parkir motor = 2000
total = 2000 × 40
total = 80.000

banyak uang parkir
= 100.000 + 80.000
= 180.000 ➡B.

semoga membantu

Mobil = x
Motor = y

x + y = 60 (i)
4x + 2y = 160 (ii)

(i) × 2
2x + 2y = 120 (iii)

(ii) - (iii)
2x = 40
x = 20

x + y = 60
20 + y = 60
y = 40

x.5000 + y.2000
= 200.5000 + 40.2000
= 100000 + 80000
= Rp180.000
