Unformatted text preview: x =23 t. In the second equation the leading variable is y, and we get y = 1 + 2 t. We recognize these as parametric equations of a line, with vector form [ x, y, z ] = [2 , 1 , 0] + t [3 , 2 , 1] , which is our solution of this linear system. 2 1. For the system 2 x 1 + 2 x 23 x 4 = 0x 1x 2 + x 3 + x 4x 5 = 2 x 1 + x 2 + x 32 x 4x 5 = 2 the augmented matrix is 2 2311 1 11 2 1 1 121 2 . Solution:...
