Abstract
. System of 2 Linear Equations with two unknown variable, presented in canonical form:
A
1
X + B
1
Y = C
1
A
2
X + B
2
Y = C
2
has a symbolic solution (based on Cramer's Rule) using Determinant (
Det
) as following:
Det
=
A
1
*
B
2
-
A
2
*
B
1
X = ( B
2
* C
1
- B
1
* C
2
) /
Det
y = ( A
1
* C
2
- A
2
* C
1
) /
Det
If
Det
=
0
there is no solution.
If
C
1
=
C
2
=
0
, then the trivial solution will be: X = Y = 0.

. If any of Text Boxes
A1, A2 or B1, B2
are left empty, system will automatically assign number 1 to corresponding coefficients.
