RESOLUÇÃO DE SISTEMA DE DUAS EQUAÇÕES DO 1.º GRAU A DUAS INCÓGNITAS PELO MÉTODO DE ADIÇÃO

Abstract

The present study is aimed at solving a system of two 1st grade equations with two unknowns using the addition/reduction method, one of the themes that has been a reason for difficulties in learning Mathematics for 9th grade students. class in Angola. It aims to answer the Scientific Problem: how to develop skills in solving this issue at Colégio 4 de Abril do Sumbe, Province of Cuanza-Sul? Its objective is to solve exercises and problems inherent to the system of two 1st degree equations with two unknowns using the addition/reduction method, with a view to improving the Teaching-Learning process. It is a qualitative investigation, with a descriptive approach, with the use of theoretical, empirical and mathematical-statistical methods. We used the interview and survey by questionnaire. It is expected with this study, the development of learning.
