Question

(1 pt) We say two matrices A and B commute with each other if $AB = BA$. Consider $A = \begin{bmatrix} 1 & 0 \\ 4 & 1 \end{bmatrix}$ and $B = \begin{bmatrix} w & x \\ y & z \end{bmatrix}$. Identify the conditions that must be satisfied by B in order for it to commute with A. Enter your answer as a comma-separated list of linear equations involving w, x, y, z. Use the fewest number of equations that are necessary to guarantee A and B commute.

We say two matrices A and B commute with each other if AB = BA. To determine the conditions that must be satisfied by B in order for it to commute with A, we can set up a system of linear equations involving the variables w, x, y, and z. The equations can be written as follows: 1) Z = w + 4x 2) X = y These equations are the fewest number of equations necessary to guarantee that A and B commute.
