Soal sistem persamaan linear dan variabel1. x + 3y = 15 3x + 6y = 302. 3x + 5y = 16 4x + y = 10Tolong jawab menggunakan kertas, atau chat GPT!! ​

Jawaban:No 1. [tex]x + 3y = 15 \\ 3x + 6y = 30 \\ x = 15 - 3y \\ 3 \times ( - 3y + 15) + 6y = 30 \\ - 9y + 45 + 6y = 30 \\ - 3y = 30 - 45 \\ - 3y = - 15 \\ y = - 15 \div - 3 \\ y = 5 \\ \\ x + 3y = 15 \\ x + 3 \times 5 = 15 \\ x + 15 = 15 \\ x = 15 - 15 \\ x = 0[/tex]No 2. [tex]3x + 5y = 16 \\ 4x + y = 10 \\ \\ y = 10 - 4x \\ \\ 3x + 5 \times (10 - 4x) = 16 \\ 3x + 50 - 20x = 16 \\ - 17x = 16 - 50 \\ - 17x = - 34 \\ x = - 34 \div - 17 \\ x = 2 \\ \\ y = 10 - 4x \\ y = 10 - 4 \times 2 \\ y = 10 - 8 \\ y = 2[/tex]Bulan redup diselimuti mega,Angin malam menari perlahan.Manusia hidup tak luput dosa,Namun ampunan selalu Tuhan sediakan.
