Uang yang dikeluarkan Liling di hari Senin dan Selasa secara berturut-turut adalah 10$, dan 300$. Penjelasan:Misalkan s adalah uang yang dikeluarkan Liling pada hari Minggu, m adalah uang yang dikeluarkan pada hari Senin, dan t adalah uang yang dikeluarkan pada hari Selasa, maka:s = m + 140t = 2ss + m + t = 460 Karena t = 2s, maka substitusi t dengan 2s (di persamaan s + m + t):s + m + 2s = 460Selanjutnya, karena s = m + 140, substitusi s dengan m + 140.m + 140 + m + 2(m + 140) = 460Selanjutnya kita perlu menyederhanakan. Kita akan mengubah bentuk a(b + c) menjadi ab + ac agar bisa menjumlahkan koefisiennya dan konstantanya. Maka:m + 140 + m + 2m + 280 = 460Lanjut sederhanakan dengan menjumlahkan koefisien dan konstanta:4m + 420 = 460Kurangi kedua ruas dengan 4204m = 40Lalu, kita tinggal mendapatkan nilai m dengan membagi kedua ruas dengan 4.m = 10Sekarang, kita ingin tahu berapa uang yang dikeluarkan Liling pada hari Selasa. Kita bisa mendapatkannya dengan substitusi. Pertama, dari persamaan t = 2s, substitusi s dengan m + 140.t = 2(m + 140)Selanjutnya karena nilai m sudah diketahui yaitu 10, substitusi m dengan 10:t = 2(10 + 140)Lanjut:t = 2(150)t = 300 Sehingga, uang yang dikeluarkan Liling pada hari Senin adalah 10$, sementara pada hari Selasa, uang yang dikeluarkan adalah 300$.

Uang yang dikeluarkan Liling di hari Senin dan Selasa secara berturut-turut adalah 10$, dan 300$.

Penjelasan:

Misalkan s adalah uang yang dikeluarkan Liling pada hari Minggu, m adalah uang yang dikeluarkan pada hari Senin, dan t adalah uang yang dikeluarkan pada hari Selasa, maka:

s = m + 140

t = 2s

s + m + t = 460

Karena t = 2s, maka substitusi t dengan 2s (di persamaan s + m + t):

s + m + 2s = 460

Selanjutnya, karena s = m + 140, substitusi s dengan m + 140.

m + 140 + m + 2(m + 140) = 460

Selanjutnya kita perlu menyederhanakan. Kita akan mengubah bentuk a(b + c) menjadi ab + ac agar bisa menjumlahkan koefisiennya dan konstantanya. Maka:

m + 140 + m + 2m + 280 = 460

Lanjut sederhanakan dengan menjumlahkan koefisien dan konstanta:

4m + 420 = 460

Kurangi kedua ruas dengan 420

4m = 40

Lalu, kita tinggal mendapatkan nilai m dengan membagi kedua ruas dengan 4.

m = 10

Sekarang, kita ingin tahu berapa uang yang dikeluarkan Liling pada hari Selasa. Kita bisa mendapatkannya dengan substitusi. Pertama, dari persamaan t = 2s, substitusi s dengan m + 140.

t = 2(m + 140)

Selanjutnya karena nilai m sudah diketahui yaitu 10, substitusi m dengan 10:

t = 2(10 + 140)

Lanjut:

t = 2(150)

t = 300

Sehingga, uang yang dikeluarkan Liling pada hari Senin adalah 10$, sementara pada hari Selasa, uang yang dikeluarkan adalah 300$.
