Find the least squares solutions to the following linear systems: (a) x + 2y = 1, 3at
Question:
(a) x + 2y = 1, 3at - y = 0, -x +2y = 3,
(b) 4x-2y = 1, 2x+3y = -4, x - 2y = - 1, 2x + 2y = 2,
(c) 2u + v - 2w = 1,3u-2w = 0, k-v+3w = 2,
(d) x - z = - 1, 2.x - y + 3z = 1, y - 3z = 0, -5x + 2y + z = 3,
(e) x1 + x2 = 2, x2 + x4 = 1. X1 + x3 = 0, x3 - x4 = 1, x1 - x4 = 2.
