Answer:
The solution for this system is: 
Step-by-step explanation:
The problem states that we have to solve this system by the elimination method
In the elimination method, we transform the system in such a way that one variable can cancel each other. With this, we find the result of the other variable. Then, we can replace the variable we found in any of the equations, and we have the value of the variable that we had initially canceled.
In this problem, we have the following system:


If we add equations 1) and 2), the variable x is going to be eliminated





Now, we can replace the value of y in any of the equations, to find x:
I will replace in equation 2)





The solution for this system is: 
Answer:
Ok so first you would have to turn them into improper fractions which is
3
=
and 4
= 
So now that you have made them both improper fractions you have to find common denominators.
To find common denominators you must multiply both the numerator and the denominator by the same thing. Since your oposing fraction has a denominator of 5 you can know that a even number wont go in an odd number so take
and mutiply both numbers by 2 and get
. Then mutiply both numbers in
by 5 to get a common denominator.

=35 - 44 = -9 so your answer is 
Step-by-step explanation:
F(x) = x (x^3 - x^2 + x + 1)
Found this when I was doing my own work, hope this helps.
