Which of the following statements is true of the system below? –2x – 3y = –1 3x + 6y = 0

The solution to the system is (2,-1) 
To make sure plug in the ordered pair into the system of equations

-2(2) - 3(-1) = -1
-4 - (-3) = -1
-1 = -1

3(2) + 6(-1) = 0
6 + -6 = 0
0 = 0
This ordered pair works and is your answer
(2,-1)
