Solution:
Explanation of Solution
Given:
Calculation:
The original system of equations can be written compactly as a matrix equation.
Where,
To solve the for
Multiply both sides by
By association property of matrix multiplication, the above equation can be rewritten as:
By the defmition of inverse matrix
By the property of Identity matrix,
Hence,
i.e.
Determining
Step 1: Construction of
Step 2: Transform the matrix
Step 3: Separate the matrix on the right of the vertical bar which is the inverse of
Solving
