TEST BANK FOR Applied Linear Algebra By Peter J. Olver and Chehrzad Shakiban

1.1.1. (a) Reduce the system to x − y = 7, 3y = −4; then use Back Substitution to solve for x = 17 3 , y = − 4 3 . (b) Reduce the system to 6u + v = 5, − 5 2 v = 5 2 ; then use Back Substitution to solve for u = 1, v = −1. (c) Reduce the system to p + q − r = 0, −3q + 5r = 3, −r = 6; then solve for p = 5, q = −11, r = −6. (d) Reduce the system to 2u − v + 2w = 2, − 3 2 v + 4w = 2, −w = 0; then solve for u = 1 3 , v = − 4 3 ,w = 0. (e) Reduce the system...
