Write the following system as a matrix equation involving the product of a matrix and a vector on the left side and a vector on the right side
2x₁ + x₂ - 6x₃ = -6
6x₁ - 4x₂ = 2

a. [x₁, x₂, x₃][2] [-6]
[6, -4, 0][1] = [2]
[-6]
b. [2, 1, -6][x₁] [-6]
[6, -4, 0][x₂] = [2]
[x₃]
c. [2, 1, -6][x₁] [-6]
[6, 4, 1][x₂] = [2]
[x₃]
d. [2, 6][x₁] [-6]
[1, -4][x₂] = [2]
[-6, 0]
