No, Crammer’s Rule isn’t always
applicable when trying to solve a system of linear equations because let’s say
for example, i<span>f the determinant of the coefficient matrix is 0,
then Cramer's rule cannot be applied. This
usually happens there’s no solution or an infinite number of solutions. </span><span>In
linear algebra, </span>Cramer's rule<span> is
an explicit formula for the solution of a system of linear equations with as
many equations as unknowns, valid whenever the system has a unique solution.</span>
I am hoping that this answer has satisfied your query and it will be
