Answer:

Explanation in link:

The equation has a infinite number of solutions.

Step-by-step explanation:

-6x - y = -27

18x + 3y = 81

-6x - y = 27

+6x —-+6x

-Y = 27 + 6x

Then, divide both sides by negative one to get rid of that negative y:

Y = -6x + 27

Now replace the Ys in the other equation with -6x + 27.

18x + 3(-6x + 27) = 81.

Do distribute property

18x + -18x + 81 = 81

The 18x and -18x cancel each other out.

81 = 81.
