Yes you can, if the solution or solutions is/are real.
-- Draw the graphs of both equations on the same coordinate space on the
same piece of graph paper.
-- Any point that's on both graphs, i.e. where they cross, is a solution of the
system of equations.
-- If both equations are linear, then there can't be more than one such point.
Graph the equation then find the x intercepts.
The points of intersection are normally the solutions of the equations for x and y
To solve a system of equations, you need equations (number phrases with equal signs).
The answer depends on whether they are linear, non-linear, differential or other types of equations.
You can write an equivalent equation from a selected equation in the system of equations to isolate a variable. You can then take that variable and substitute it into the other equations. Then you will have a system of equations with one less equation and one less variable and it will be simpler to solve.

This looks like a question from a Virtual School course - please ask you teacher for help and use the examples in the lesson.
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).
y=3x-4 y=-2x+1
I have never seen the term 'symbolic' used in this way. There are 4 methods used to solve a system of linear equations in two variables. Graphing, Substitution, Elimination, and Cramer's Rule.
graphing method is when you graph two lines and then find the intersection which is the answer of the system of equations
A graph can help you understand equations better its a little way of getting used to a a problem. I used a multiplication graph when i was 10 it helped me memorize the problem.
-- 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.
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.
The solution is the coordinates of the point where the graphs of the equations intersect.
Write each equations in popular form. ... Make the coefficients of one variable opposites. ... Add the equations ensuing from Step two to remove one variable. Solve for the last variable. Substitute the answer from Step four into one of the unique equations.
