-- Graph each equation individually.
-- Examine the graph to find points where the individual graphs intersect.
-- The points where the individual graphs intersect are the solutions of the system of equations.

In systems of equations, the graphing method is solving x and y by graphing out the two equations. x and y being the coordinates of the two line's intersection.
You can use a graph to solve systems of equations by plotting the two equations to see where they intersect
very possible, unless there is something preventing them from being true, like an undefined answer. The most common ways are through substitution, graphing, and elimination.
Graph the equation then find the x intercepts.
A graphing calculator is used to plot graphs and solve equations. Most graphing calculators are programmable so one can create customized programs.
By graphing the lines on the coordinated plane they will intersect at (2, -4) which is the solution of the equations
Substitution is a way to solve without graphing, and sometimes there are equations that are impossible or very difficult to graph that are easier to just substitute. Mostly though, it is a way to solve if you have no calculator or cannot use one (for a test or worksheet).
This looks like a question from a Virtual School course - please ask you teacher for help and use the examples in the lesson.
Which of the following is a disadvantage to using equations?
solve systems of up to 29 simultaneous equations.
because you need maths in your life.. everyone does
