Gotta Math 'Em All!

Welcome to the world of Pokémon and matematics!

For some people, Pokémon are pets. Others use them for fights. In this place, we help Pokémon solve mathematical problems!

Rules:

  1. Calculators are prohibited.
  2. All equations should be solved for x.
  3. Write the solution(s) in the text field and submit.
  4. Write fractions in simplest form. Example: 2/4 → 1/2.
  5. Don't write denominator of 1. Example: 3/1 → 3.
  6. Answer with a fraction instead of decimal. Example: 0.75 → 3/4.
  7. When there are two solutions for x, give both answers comma separated, with the lowest number first. Example: -1/3,1/3.

Your very own legend is about to unfold! A world of equations and adventures with Pokémon awaits! Let's go!
