Given the linear systems (a) x1 + 2x2 = 2 3x1 + 7x2 = 8 (b) x1 + 2x2 = 1 3x1 + 7x2 = 7

Chapter 1, Problem 11

(choose chapter or problem)

Given the linear systems (a) x1 + 2x2 = 2 3x1 + 7x2 = 8 (b) x1 + 2x2 = 1 3x1 + 7x2 = 7 solve both systems by incorporating the right-hand sides into a 2 2 matrix B and computing the reduced row echelon form of (A|B) = 1 2 2 1 3 7 8 7 1
