Aprenda a Resolver Sistemas com 3 Incógnitas (O Jeito Mais Fácil!) 🤯

Solving a system with X and Y is already challenging, imagine adding Z to the equation! But don't worry: today I'm going to teach you the Gaussian Elimination technique, which transforms this three-headed monster into simple calculations you already know how to do. The secret isn't doing everything at once, but following a "recipe" in 3 steps: 🚀 The Gaussian Elimination Step-by-Step: Choose a main equation (your "anchor"). Choose a letter to eliminate (in our case, we chose to "kill" Z). Compare the main equation with the others, creating a much simpler 2x2 system. 🔗 Prerequisite: Don't know how to solve systems with two letters yet?
