Answer:
x = 20
Step-by-step explanation:
I'm no mathematician but...
- 4 = x / 20 - 5
If you move the five to the other side using addition you get:
1 = x / 20
Then multiply 20 on both sides
20 = x
-13,4, - 9/2 is the answer :)
The restriction of the expression as given in the task content is; x +y = 0.
<h3>What is the restriction of the expression?</h3>
The expression in the task content is rational;
(1-x-y)/(x+y).
On this note, the restriction to the expression is the values which render the denominator of the expression equal to 0 and consequently the expression value to undefined.
Hence, the restriction is; x+y = 0.

Let n be the amount of points earned in round 5
the goal of the game is to get zero when you add up the point value from all the rounds.
this means
-9 +3 + (-8)+ 2 +n =0
add up all the given numbers, then see which number(n) is required in order to get zero
any questions?
