Methods Of Solving Systems Of Equations - Paper

Methods Of Solving Systems Of Equations

Whenever there is something to do, there are always many ways to do
it. This hold true with solving systems of equations. To solve the systems,
there are five main methods to use. These methods include solving by
graphing, substitution, linear combination, inverse matrices, and Cramer’s
Rule.
Solving by graphing is one of the simplest ways to solve an
equation. In order to solve this way, the equations in the system need to
be in slope intercept form. After the equations are in slope intercept form,
you can plot them easily using the slope and y intercept. Once the lines
are graphed, one of three things may occur. There may be one solution, no
solution, or many solutions. There will be ...

accurate. Although it seems easy, this
is not one of my preferred methods of solving systems of equations because
it is not always easy to graph lines and to determine a point of
intersection from a graph.
One of the easiest ways to solve a system of equations is to solve
by substitution. In order to use this method, it is preferable that either
the x or the y in one of the lines has no coefficient. The method will work
if there are coefficients before the variables, but it is easier if one of
the variables is coefficient free. To begin this method, decide which
variable you want to use, and isolate it. Once the variable is isolated,
take the value for that variable and plug it into the other equation
instead of the isolated variable. Then, solve for the one variable left in
the equation. Now substitute the answer for the variable into the original
equation, and solve for the isolated variable. This is a quick method to
use when there is a variable with no coefficient. If all of ...
