Graphing, substitution, linear combination

Algebra is a mathematical system. It involves letters, numbers, symbols, and a variety of equations. Equations are systems of inequality between two expressions. There are many types of equations. In the paragraphs below I will introduce to you three different systems of equations and how to solve them. One way to solve an equation is to graph. There are three different steps in graphing equations to solve. The first thing you want to do is …showed first 75 words of 512 total…

I have now introduced you to three different systems of equations : graphing, substitution, and linear combination. Out of all of the systems, I prefer linear combination. I find it to be the quickest and simplest method. I believe that these three systems are easy to understand and are very helpful in the learning process of Algebra.
