The two methods of solving for systems of linear equations algebraically are the methods of substitution and elimination.
The goal of the method of substitution is to reduce a system of two linear equations in two variables to a single equation in one
variable.
The key step in using method of elimination is to obtain opposite coefficients for one of the variables so that adding the two equations eliminates this variable.
Solving systems of linear equations by graphing involves sketching the lines representing the equations to determine whether the lines intersect at a point, which is the solution of the system.
