Himpunan penyelesaian sistem persamaan linear dua variabel2x - y = -3x + 3y = 2Langkah Penyelesaian:Kita selesaikan sistem persamaan berikut: 1. 2x - y = -3 → (Persamaan 1) 2. x + 3y = 2 → (Persamaan 2)Langkah 1: Eliminasi atau substitusiKita gunakan substitusi. Dari persamaan (2):x = 2 - 3yMasukkan ke persamaan (1):2(2 - 3y) - y = -3 4 - 6y - y = -3 4 - 7y = -3 -7y = -7 => y = 1Substitusi nilai y = 1 ke persamaan (2):x + 3(1) = 2 => x = 2 - 3 = -1Himpunan penyelesaiannya adalah:(-1, 1)
