Pertanyaan
(1) Selesaikan sistem persamaan berikut dengan menggunakan metrit gratik. to ) x-y=2 3x+y=26 (1) ) 4x-8y=-2 x-2y=-(1)/(2) Penerapan Konsep
Jawaban
1) x=13, y=11
2) x=1, y=2
Penjelasan
Untuk soal pertama kita akan menggunakan metode substitusi, misal x=n. Maka dari {x-y=2}, bisa kita ubah menjadi y=n-2. Kemudian kita masukan hasil tersebut (y=n-2) ke persamaan dibawah nya yang 3x + y =36 atau kita ubah menjadi 3x + n-2 = 36. Setelah kita selesaian hasilnya adalah 37. Kita masukkan hasil x kedalam salah satu persamaan dan di hasilkan y=11 dan x=13.
Demikian dengan soal kedua untuk persamaan 1 bisa di tulis menjadi y = (4x + 2)/8 atau y = x/2 - 1/4 yang kita kita masukkan ketika persamaan 2 atau hasil dari y kita masukkan kedalam x-2y=-1/2 sehingga menjadi x-2(x/2 - 1/4)=-1/2. Lalu kita selesaikan hasilnya x=1 dan y=2. Setelah mempunyai nilai x dan y kita bisa anda tes untuk mengetahui kebenaran hasil solusi kamu cukup dengan memasukkan nilai masing masing variabel dan jika nilai kiri dan kanan sama berati kamu telah berhasil meneyelsaikan soal tersebut. Jadinya jawaban yang benar 1) x = 13, y = 11 2) x = 1, y = 2
