Hello, Amber!
Do you have a clue on how to solve this??

anonymous · Answer

D

anonymous · Answer

Notice that if you try to solve by elimination, you could multiply the second equation by 3 and you would get this set

6x-9y=-9
6x-9y=-18

From here, try subtracting the second equation from the first and see what you get
