нatrix A 3D |2 5 2 -4 -1, suppose azn is the pivot. This means that Row ? v is being zeroed out by multiplying Row ? v by 7 t to Row 2. This also means that Row ? v is being zeroed out by multiplying Row ? by 2, and adding it to Row v operations by multiplying on the left of A by the matrix M = I at a11, we determine
