The steps are :

x + 2y = 13 -  -  - (1)

- x + y = 5 -  -  - (2)

(1) + (2)

x + 2y + ( - x) + y = 13 + 5

3y = 18

y = 6

substitute \: y = 6 \: into \: (2)

(2)⇒

- x + 6 = 5

- x =  - 1

x = 1

Therefore, you have to insert the values into the coordinates form so the answer willl be (1 , 6).

Well I don't know ! 
Let's take a look and see:

The idea is that there could be more than one way
for a roll of the dice to land with the same number.  

-- If the sum is from 1-4, you get the point.
There are  6  different ways for a roll of the dice to come up 1-4.

-- If the sum is from 5-8, Adam gets the point.
There are  20  different ways for a roll of the dice to come up 5-8.

-- If the sum is 9-12, Lana gets the point.
There are  10  different ways for a roll of the dice to come up 9-12.

-- The game is not fair to all three of you.
-- Lana has a distinct advantage over you.
-- Adam has a big advantage over Lana.
-- Adam has an even bigger advantage over you.
-- You are at a big disadvantage.  (Notice that one of your
numbers ... 1 ... can never come up unless one of the dice
falls off of the table.)
