incase of 3x3 determinants if we use cramer,s rule.And the result is dependent and has infinitely solution.How will I get the solutions.(Main point is we have three variables x,y,z)

Question

amistre64 · Answer

an infinite number of solutions suggests that the system of equation is either 3 planes that are the same plane, or that they all intersect in a common line

amistre64 · Answer

the solution set of infinite solutions is the equation of the solution set itself.
