No Solution to 3 Linear Equations Using Cramer's Rule

[phymatter]

while solving 3 linear equations in 3 variables by cramer's rule if all the determinant's are 0 then what can we conclude?

if Ax=b
det(A)=0
we get 3 linearly dependent equations, hence you can construct infinite solutions to the equations.
