Sistema de Equações do Primeiro Grau | Ensino Fundamental [7 ANO / 8 ANO]

In this class, you will become a master in the System of First-degree Equations using the substitution method to solve a system of first-degree equations with two unknowns in a practical way and with exercises. In addition to teaching you how to solve a system of first-degree equations directly using the substitution method, I will also show you how to solve problems with systems of first-degree equations. This subject is studied in the 7th and 8th grades of elementary school, how to set up and solve a system of equations. Study with me and be successful in Mathematics.
