Show at least the first step of your work as you solve this system by elimination. provide your final answer as an ordered pair.

5x+4y=-14

3x+6y=6

Well if you use the subtraction method for elimination you get 
2x+-2y=12
Now you can times one at a time by zero and find what each equals.
2(0) +-2y=12
y=-6
2x+-2(0)=12
x=6
