Question

Is the system of equations is consistent, consistent and coincident, or inconsistent?

y = -x - 1

3y = -3x + 12

consistent

consistent and coincident

inconsistent

Answer 1

You can trust on above answer

Answer 2

C.) Inconsistent....

Multiply first eqn by 3,

3y = -3x-3

Now, compare it with 2nd one,

-3x-3 = -3x+12

-3 = 12

It can't be happen so, your answer would be Inconsistent
