Document Summary

Col 1 col 2 col 3 a12 a13 a22 a23 a32 a33. Augmented - has both sides of equation inside. Coefficient - only has left side of equation. Multiply first row by to produce new first row. Add (-2) times the first row to the third row to make a new third row. R3 + (-2) * r1 -> r3. Solving systems with augmented matrices: make all values: a11, a22, a33, a44, , amn = 1, triangle beneath above values = 0. Col 1 col 2 col 3 | col 4 a12 a13 | a14 a22 a23 | a24 a32 a33. For not all-zero row, first coeff. must be 1. Only 1"s in matrix (besides last column) Col 1 col 2 col 3 | col 4 a12 a13 | a14 a23 | a24. Col 1 col 2 col 3 | col 4 a12 a13 | a14.
