Answer:12063.72
Step-by-step explanation:
There are 3 ways of solving a simultaneous problem, substitution method, elimination method and Gauss-Jordan method. I'm gonna use the substitution method since it's easier and i think it would suit your level more.
First let's try solving for y since it's easier to start with.
Firstly we have to find an equation for x:

Great, now we can use the substitution method to find the value of y using the first equation:

Now we know that y=1 we can solve the first equation we made:

And the answer is 
Double check:

And that's our final answer! (4,1)
<span>Round (x) 1 2 3 4 5
Players f(x) 256 128 64 32 16
16-256 / 5 - 1 = -240/4 = -60
</span><span>A.) −60; on average, there was a loss of 60 each round. </span>
16x
Both of these expressions are similar expressions, therefore you can simply add the number in front of the 'x'
6 + 10 = 16
Therefore, 6x + 10x = 16x
