- Can a matrix with zeros on the diagonal have an inverse? If so, find an example. If not, prove why not. For simplicity, assume a 22 matrix.arrow_forwardWrite the system of equations that corresponds to the augmented matrix: [111423181113] .arrow_forwardCan a matrix whose entry is 0 on the diagonal be solved? Explain why or why not. What would you do to remedy the situation?arrow_forward
- Solve for x and y in the matrix equation 2AB=I, given A=[1123] and B=[x2y5].arrow_forwardCan you explain whether a 2×2 matrix with an entire row of zeros can have an inverse?arrow_forwardIs there only one correct method of using row operations on a matrix?
