Solution:
Using Matrices to Solve System of Linear Equation (Cramer’s Rule)
Matrices and their determinant can be used to solve a system of equations. This method becomes
especially attractive when large numbers of unknowns are involved. But the method is still
useful in solving algebraic equations containing two and three unknowns.
In part one of this chapter, it was shown that equations could be organized such that their
coefficients could be written as a matrix.
ax + by = c
ex + fy = g
where:
x and y are variables
a, b, e, and f are the coefficients
c and g are constants
