Explanation Given: The given matrix is, T = [ 0.3 0.2 0.5 0.1 0.8 0.1 0.4 0.3 0.3 ] Approach: The equilibrium matrix L can be solved by following steps. 1. Create the transition matrix T . 2. Create the equilibrium matrix L . 3. Find and simplify the system of equations described by L T = L . 4. Discard any redundant equations, and include the equation x + y + z = 1 (or similar if there are more than three variables). 5. Solve the resulting system, using either the elimination method or the graphing calculator method. 6. Check your work by verifying that L T = L . Calculation: Consider the equilibrium matrix, L = [ x y z ] Find and simplify the system of equations described by L T = L as follows, [ x y z ] [ 0.3 0.2 0.5 0.1 0.8 0.1 0.4 0.3 0.3 ] = [ x y z ] Multiply the Matrix as follows, [ 0.3 x + 0.1 y + 0.4 z 0.2 x + 0.8 y + 0.3 z 0.5 x + 0.1 y + 0.3 z ] = [ x y z ] Equate both the side equations as follows, 0.3 x + 0.1 y + 0.4 z = x 0.2 x + 0.8 y + 0.3 z = y 0.5 x + 0.1 y + 0.3 z = z The above equations can be written as follows, − 0.7 x + 0.1 y + 0.4 z = 0 0.2 x − 0.2 y + 0.3 z = 0 0.5 x + 0.1 y − 0.7 z = 0 Multiply with 10 to the above equations. − 7 x + 1 y + 4 z = 0 …… ( 1 ) 2 x − 2 y + 3 z = 0 ...... ( 2 ) 5 x + 1 y − 7 z = 0 …… ( 3 ) L = [ x y z ] is a probability equation so sum of its entries must be equal to 1 that means, x + y + z = 1 …… ( 4 ) Multiply with − 2 in equation ( 4 ) and add the results with equation ( 2 ) as follows, 2 x − 2 y + 3 z = 0 − 2 x − 2 y − 2 z = − 2 _ To determine (b) To verify: The solution L T = L .
