What are the 3 methods for solving systems of equations?
There are three ways to solve systems of linear equations in two variables: graphing.
What is the result of adding two equations?
Adding the equations means that we add the left sides of the two equations together, and we add the right sides together. This is legal because of the Addition Principle, which says that we can add the same amount to both sides of an equation.
How do you solve two equations with two variables?
The Method of Elimination: In a two-variable problem rewrite the equations so that when the equations are added, one of the variables is eliminated, and then solve for the remaining variable. Step 1: Multiply equation (1) by -5 and add it to equation (2) to form equation (3) with just one variable.
