Question

Classify the system and determine the number of solutions. (Check all that apply. )

{7x - y = -11
3y = 21x + 33


infinitely many solutions

independent

consistent

no solution

inconsistent

dependent

Answer 1

What say you? Have you a plan?

Hint1: If you get this, x = something nice and y = something nice, that's consistent with one solution.

Hint2: If you get something really silly, like 0 = 4, that is inconsistent.

Hint3: If you get something totally obvious, 7 = 7, that s consistent, but with many solutions. Is this what "dependent" means?
