Answer:
The third option
Step-by-step explanation:
One thing that we can do with two equations in a system of equations is add them together. If we do that with these equations, we get
[tex]3x^{5} + 4x^{4} - 5x^{3} + 6x^{3} + 2x^{2} - 10x + 4 - 11 = 2y\\3x^{5} + 4x^{4} + x^{3} + 2x^{2} -10x - 7 = 2y[/tex]
In the addition, I simply combined like terms (where the variable was the same, and the x was to the same degree, e.g. -5x^3 + 6x^3 are both to the third degree, and the result is x^3). If we make y 0, our answer is the third option.
