Solve parts a and b below given the following information. w - x + 2y = 3 x - y

Question

Solve parts a and b below given the following information. w - x + 2y = 3 x - y + z = -5 - w + x - y + 2z = 1 - x + y - 2z = -2 The inverse of [1 -1 2 0 0 1 -1 1 -1 1 -1 2 0 - 1 1 -2] is [0 0 -1 -1 1 4 1 3 1 2 1 2 0 -1 0 -1] Write the linear system as a matrix equation in the form AX= B. Solve the system using the inverse that is given for the coefficient matrix. Find A and B [w x y z] = (Type an integer or simplified fraction for each matrix element.) The solution set is (Type integers or simplified fractions.)

Explanation / Answer

Question is again not clearly visible but I will tell you the way to solve it.

We should use AX = B.

We have been given 4 equations in w, x, y and z. We can solve these 4 equations to find out the values of 4 unknown variables which are w, x, y and z.

Then directly by putting it in the given equation, we will get the value of A and B.
