Find the dimension and a basis for the solution space. (If an answer does not exist, enter DNE for the dimension and in any cell of the vector.)
X₁ + 2x₂ − 3x3 - 11x4 + 8x5 = 0
X₁ + 3x3 + x4 + 6x5
= 0
2x₁ + 6x₂ - 12x3 34x4 + 18x5

A basis for a solution space consists of linearly independent vectors that span the space. The dimension of the solution space is determined by the number of vectors in the basis. One way to obtain
possible vectors is by solving an augmented matrix. What is the augmented matrix for this system of equations? How can a solution be obtained from the augmented matrix?
