How to solve system of equations addition

WebElimination works because it eliminates one of the variables, we can solve the equation only if there is 1 variable and not 2 variables. This system of equation was super easy because you could eliminate the x variable right off the bat because x -x =0, so we cancel those two out and were left with just 1 variable in the equation, y, and then we can just solve it. WebSolving Systems of Equations in Two Variables by the Addition Method A third method of solving systems of linear equations is the addition method, this method is also called the elimination method. In this method, we add two terms with the same variable, but opposite coefficients, so that the sum is zero.
