Consider the homogeneous system of linear equations. For convenience, their general solution is given. It can be shown that the solution of the system forms a subspace W of some R". Find a basis for the subspace of the solution and give dimension. x + x8x3 + 10x = 0 x2 - x3 + 3x40 X + 2x9x3 + 13x4 0 The general solution is (7r - 7s, r- 3s, r, s). basis dimension Give written description of the subspace. O a plane through the origin of R O a three-dimensional subspace of R O a line through the origin of R O a line through the origin of R O a plane through the origin of R
