For a square matrix 𝐴 of order 𝑛 × 𝑛, the “multiplicative inverse” (if it exists) is a square matrix 𝐴 such that 𝐴 𝐴 = 𝐼 = 𝐴 𝐴, where 𝐼 is the 𝑛 × 𝑛 identity matrix. Necessarily, the matrix 𝐴 would also be a square matrix of order 𝑛 × 𝑛.

WebJan 27, 2024 · To solve this system, the matrix has to be reduced into reduced echelon form. Step 1: Switch row 1 and row 3. All leading zeros are now below non-zero leading entries. Step 2: Set row 2 to row 2 plus (-1) times row 1. In other words, subtract row 1 from row 2. This will eliminate the first entry of row 2. Step 3: Multiply row 2 by 3 and row 3 by 2.
