WebJan 4, 2024 · Having a -3 in the (3, 1) place in E means that the third row has 3 times the first row subtracted from it. We can see where this comes from — our first step of elimination (E21) is to subtract 2 times the first row away from the second row. Our second step (E31) is to subtract 1 times the first row away from the third row.
