📊 Matriks Awal

Perhitungan Determinan |A|:

📐 Metode 1: Adjoint

1. Minor M_ij

Minor = determinan 2×2 dari submatriks

2. Kofaktor α_ij = (-1)^i+j × M_ij

3. Adj(A) = K^T

4. A^-1 = (1/|A|) × Adj(A)

🔄 Metode 2: Counter (OBE)

Operasi Baris Elementer pada [A | I] → [I | A^-1]

Ekstrak A^-1 (bagian kanan):

✅ HASIL AKHIR A^-1
