How many solutions does the system of equations have?

y = - 2x + 9

6x + 3y = 27

A) one

B) two

C) infinitely many

D) none

As 27 will always be equal to 27, you can place whatever you want for x and y and the equation would still be satisfied, as it turns out that it doesn't depend on the x or y value.

Therefore, the system has infinite solutions.

Be safe!

C. Infinitely many

I just took the test.
