please solve B7. give me a handwritten solution as it is comfortable for me to understand.

For Problems B7-BI2, determine whether the matrix is a Markov matrix. If so, determine the invariant or fixed state (corresponding to the eigenvalue / = 1). By 0.4 0.7 0.6 0.5 since the 10.6 0.3 0.5 0.4 not a M 0.9 0.2 0.3 0.7] 0.1 0.8 B10 0.2 0.8
