What is the importance of the tertiary structure of a tRNA? I know the structure, but I'm not sure what is the importance of it. Is it stabilization?

Algebra
2(x+5)/(x+5)(x-2) = 3(x-2)/(x-2)(x+5) + 10/(x+5)(x-2) I know I have to get 2(x+5) = 3(x-2) but I don't know the intermediate steps. I tried canceling out to get 2/(x-2) = 3 + 10 / (x+5) and gross multiplying but that wouldn't make sense.
