supposed to make y the subject of the equation

supposed to make y the subject of the equation
Why? You fond dy/dx, so you can just find the equation of tangent after that.
Not quite sure what you're trying to do after dy/dx = (2x - 8e^(x + y))/(8e^(x + y) - 2y).

so after finding the dy/dx of the C curve, we compare it to the slope from the given point
right?
and after that we find the value of one of the variables (x or y)
but in order to find that value we need to make it into the subject of an equation
but to be honest, not very sure

No, why?
You have dy/dx, so just find the slope and substitute it into the equation of tangent.

hm
let me send a picture of the answer i'm attempting to follow
i'm very confused in this section

Oh, that's a different kind of problem. Yours doesn't need this.
edgy rain
You are already given a point of tangency, so just substitute the given point into the equation of tangent.

No worries, you're welcome!
