Solve for x. (type an integer or a simplified fraction. use a comma to separate answers as needed.)

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

not sure but it may be b, as i said i'm not sure.

-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
