By the 2000s, fewer than 5 percent of U.S. workers were employed in manufacturing. This decline from 40 percent in the 1950s was influenced by global competition, automation, and shifts in economic focus. Therefore, the correct answer is 'D. 5.'

Jawaban:x = 5y = 2Penjelasan dengan langkah-langkah:Kita akan menyelesaikan sistem persamaan linear dua variabel (SPLDV):[tex]4x + 2y = 16 \: (1) \\ 3x + 6y = 27 \: (2)[/tex]### Langkah 1: Samakan salah satu koefisienKita akan gunakan metode **eliminasi**. Agar mudah, kita bisa menyamakan koefisien yKoefisien y pada persamaan (1) adalah -2, dan pada (2) adalah 6Kita cari KPK dari 2 dan 6 → yaitu **6**.Kalikan:* Persamaan (1) dengan **3*** Persamaan (2) tetap$$[tex](3) \times (4x - 2y = 16) = > 12x - 6y = 48 (3) \\ 3x + 6y = 27(2)[/tex]### Langkah 2: Eliminasi $y$Jumlahkan (3) dan (2):[tex]12x - 6y + 3x + 6y = 48 + 27 \\ (12x + 3x) = 75 \\ 15x = 75 = > x = 5[/tex]### Langkah 3: Substitusi nilai x = 5 ke salah satu persamaanGunakan persamaan (1):[tex]4x - 2y = 16 \\ 4(5) - 2y = 16 \\ 20 - 2y = 16 \\ - 2y = 16 - 20 \\ - 2y = - 4 \\ y = 2[/tex]---### ✅ Jawaban:x = 5, y = 2jangan lupa terimakasih nya yaa
