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.
