Can someone please walk me through how to do this

So you just take one of the equations and multiply it to the other equation?

first equation divide each term by 2

Would it be x+y=6 then?

So you would come up with 6x+6y= 18? for the first equation and
-2x+-6=2?

-2x - 6y = 2
for the second equation, you meant (right ?)

Sorry yes thats what I meant

yes, that is what you inded come up with.

itàs ok...)

Now, add the equations

6x + 6y = 18
-2x - 6y = 2

Okay so it would be 4x + 18y = 20?

Oh wait 12y*

18y?

Oh so it would be 4x = 20?

so x is?

5?

yes, that is correct!

Thank you so much! That makes a lot more sense now!

very nice to hear that... you are welcome!
