Solutions of Simultaneous Equations—
Determinant Method
Thisprogramsolvessimultaneouslinear equationsin twoor three un
knowns. The program uses Cramer's method, also know as the
method of determinants.
Given a system of three linear equations
AX + DY + GZ = /
BX + EY + HZ = K
CX + FY + IZ = L
the three unknowns X, Y, and Z may be computed from determinants.
