Kemudian substitusikan nilai dari variabel tersebut ke persamaan lain hingga didapatkan nilai variabel lainnya.<\/p>\n<p>Pada metode matriks, persamaan-persamaan linear dinyatakan dalam bentuk matriks, kemudian matriks tersebut dioperasikan menggunakan operasi matriks seperti invers atau determinan untuk mencari nilai variabel.<\/p>\n<h2>Kesimpulan<\/h2>\n<p>Sistem persamaan linear tiga variabel adalah kumpulan persamaan linear yang memiliki tiga variabel yang harus dicari nilainya.
