Answer:
answer B: (2,-2)
Step-by-step explanation:
First, write the equations on top of each other:

Then, multiply the the second equation by 2 so that we can use elimination of the y-variable:

Next, use elimination to find the value of "x":

So, your x-value is 2.
Now, substitute your x-value into one of your equations, let's take the second equation, 2x-y=6:

Your y-value is -2.
With all your information gathered, you find that the solution to this system of equation is (2,-2).
