jawaban + caranya dong kk lagi butuh nih :))

MAPEL = MATEMATIKA
KELAS = 8
BAB = SPLDV

misalkan :
motor = x
mobil = y

sistematika
x + y = 75
2x + 4y = 210 ➡ kenapa 2x + 4y ?
karena roda motor ada 2 dan roda mobil ada 4

Eliminasi nilai x
x + y = 75 |×2
2x + 4y = 210 |×1

2x + 2y = 150
2x + 4y = 210
___________-
-2y = -60
y = -60/-20
y = 30

Subtitusi nilai y
x + y = 75
x + 30 = 75
x = 75 - 30
x = 45

banyak motor = 45
banyak mobil = 30

biaya parkir motor = 2000
= 45 × 2000
= 90.000

biaya parkir mobil = 4000
= 30 × 4000
= 120.000

total tarif
= 120.000 + 90.000
= 210.000 ➡ A.

semoga membantu

(210-(75*2))/2 = (210-150)/2 = 60/2 = 30
Mobil  = 30 Unit / 120 Roda
Motor = 45 Unit / 90 Roda
(30*4000)+(45*2000) = 1200000+90000 = 210000

atau

Di Parkitan ada 210 Roda setiap Roda membayar parkir 1000 (Motor2000/2 dan Mobil4000/4). Jadi 210*1000 = 210000
Insyaallah Betul
