c.) If A is row-equivalent to I, and B is row equivalent to C, then AB is row equivalent to C.
d.) If A is not row equivalent to I, then the system of equation Ac = b has infinitely many solutions for any choice of b
e.) If the system of equation Ax =b has no solutions, then A is not row-equivalent to I


my guess: true, falce, true

any thoughts?
