Do you have trouble understanding first-degree equations? In this video from the Segunda Sábia series, I explain this topic in a simple, direct, and accessible way. In particular, I solve the equation 3(x + 4) = 21 using the distributive property. You'll understand how to distribute correctly, organize the terms, and isolate x to find the solution.

A simple, clear, and objective explanation to reinforce your math foundation with Professor Fernando from the Cafemática channel!
