Solving Systems of Equations Algebraically by Elimination When graphing or substitution cannot be easily done, elimination is used to solve a system of equations. Solving Systems of Equations Algebraically by Substitution. How can a system of equations be solved by elimination? So 2, 1 was a solution because, plugging in 2 for x :. You can confirm the solution by plugging it into the system of equations, and confirming that the solution works in each equation. Of course, in practical terms, you did not find solutions to an equation by picking random points, plugging them in, and checking to see if they "work" in the equation. Example Solve the following systems of equations.
A system of equations is a collection of two or more equations with a same set of unknowns. In solving a system of equations, we try to find values for each of the. We're going to learn to use a variety of methods to solve a system of equations.
