Graphing systems of equations answer key
How do you solve each system of equations by graphing?
To solve a system of equations by graphing, graph each equation and identify the point where the two lines intersect. That point is the solution to the system of equations -- it is where the x and y values of the two equations are equal. Check the solution by plugging the values into each equations.
What are the three methods for solving systems of equations?
The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices. Substitution and elimination are simple methods that can effectively solve most systems of two equations in a few straightforward steps.
How do you solve system of equations?
One way to solve this system of equations is to multiply the second equation on both sides by 3 (which doesn't alter the equality of the two sides) and then add the resulting equation from the first equation.
How do you solve linear systems without graphing?
To solve a system of linear equations without graphing, you can use the substitution method. This method works by solving one of the linear equations for one of the variables, then substituting this value for the same variable in the other linear equation and solving for the other variable.

In this section we will answer these questions. A solution to a system of linear equations is an ordered pair that satisfies each equation in the system. On the graph, to be a solution to one equation the pair must lie on the line. To be a solution to a system means the pair must be on both lines simultaneously, a point of intersection.
