A system of linear equation is a collections of linear equation with the same set of variables.
A way to solve a system of equations is with Cramer’s rule.
To solve the 2×2 matrix:
First find the determinant:
If the determinant is not zero:
> V = (X, Y)
If the determinant is zero (a/a’=b/b’):
> If a/a’ = c/c’: V = ((c-b*µ)/a, µ)
> else: V = ∅
Try it yourself:X + Y =
X + Y =
