Step-by-step explanation:





Answer:
b
Step-by-step explanation:
First subtract 8 from both sides
leaving you with x/2 = -20
Then multiply both sides by two to get rid of the denominator
which leaves you with x = -40
The answer is C because if you substitute in X-6 for the y in the first equation (since X-6 is also equal to y), you get 2x=16 which means x=8. There is only one option where 8 is equal to X, but just to check you can substitute it back into either of the original equations to make sure that y=2.
