The solution of the given system of linear equation is:
Explanation of Solution
Given information:
The following equations:
Formula used:
Inverse of a
when
Calculation:
Begin by writing the system as
Then use the given formula to find
For matrix
Because this quantity is not zero, the inverse is formed by interchanging the entries on the main diagonal, changing the signs of the other two entries, and multiplying by scalar
Finally, multiply
Hence, the solution of the given system of linear equation is
