Suppose the system AX=B is consistent and A is a 5x8 matrix and rank(A) =3. How many parameters does the solution of the system have?請幫我翻成中文，並詳解，感謝假設工程系統: A*X=B => 相容性又規模A=(5*8) => 秩=3 => 則它有多少參數?ans=3個參數對應秩=3

中譯:
suppose the system AX=B is consistent
and A is a 5x8 matrix and rank(A) =3.
假設系統 AX=B 是相容的(註: 即此聯立方程式有解),
並且 A 是 5×8 矩陣, 且 rank(A) = 3 (文: A 的秩為3).
How many parameters does the solution of the system have?
(問)此系統之解有幾個參數?

至於此題之解, 昨天回答過了.
此題之答案是: 5 個 parameters.
