Help please I’ve been stuck on this for a while

We know that the two angles are equal, so we can set the two equations for the angles equal to each other and solve for :

Let's move the terms with in them to the left side and the constants (just numbers) to the right side of the equation.

you can't solve x because it is 2 linear equation and you only have one equation

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
