Answer:
C.
Step-by-step explanation:
2x - 3y = -4
-6x + 9y = 12
Try and solve these by elimination:
Multiply the first equation by 3:
6x - 9y = -12
Now if we add this to the second equation we eliminate y, so adding:
0 = 0
- we have eliminated everything!
This means that the 2 equations are equal and there are infinite solutions.
