b.
Answer to Problem 26E
The value of the equations is obtained as,
Explanation of Solution
Given information:
The equations are given as,
Calculation:
First the determinant of the coefficient matrix must be derived as,
Since the determinant is not zero, the equation can be solved using the Cramer’s rule.
Therefore,
The value of the equations is obtained as,
