想請教這一題要怎麼解 我有點看不懂題目的意思 謝謝~

➡X a₁x+b₁y+c₁z=d₁ a₁ b₁c₁ 10. 已知三元一次聯立方程組{a2x+by+czz=d2,其係數矩陣 a b c 可簡化為 [a₂x+b₂y+c₂z = dz as b3 3. th 34/9, b yo b 00 0 C₁ a₁ b₁c₁d₁ C₂ ,則其增廣矩陣: a, b, c, d, 經過列運算簡化,可能得到下列哪 az bz cz dz 一個矩陣? (下列選項中的*代表非0且非1的數) 0 0 1 101 * (3) 0 1 0 * 0 0 0 1 (1) 0 1 0 0 100 * * 1 (2) 0 1 * b₂² 0010 「100* (4) 0 1 0 1 000*

請問這是這次112學測生要背的基本單字嗎 還是這是舊的 本人英文6級最高 有沒有什麼網站跟程式可以介紹給我加強單字的
