Solve for y in one of the equations.

4x + y = 11
Subtract 4x from both sides.
y = -4x + 11

Substitute y in the other equation.

8x + 2(-4x + 11) = 13
Simplify.
8x + -8x + 22 = 13
Subtract 22 from both sides.
0 = -9

No solutions.

\frac{d}{dx}\left(\frac{1+x^4+x^6}{x^2+x+1}\right)=\frac{4x^7+5x^6+8x^5+3x^4+4x^3-2x-1}{\left(x^2+x+1\right)^2}
