SOLVE SYSTEMS OF EQUATIONS BY GRAPHING METHOD. Solve x + y = 8 x - y = 2. Both equations are linear. Therefore, both their graphs will be lines. That is why a graph can be used to find the solution. STEPS: 1) Graph both linear equations on the same coordinate plane. 2) The point, (x, y), at which the two lines intersect is the solution to the ...

Solving Systems of Equations by Substitution **BASIC IDEA- You are taking 2 equations with 2 different variables and writing it as 1 equation with 1 variable. Example 1. Use substitution to solve the following system of equations. X + 4y = 1. 2x – 3y = -9. Step1 –Choose a variable to solve for in either equation.

Solving Systems of Linear Equations in Three Variables
To solve such a system means to find the coordinate triple (x, y, z) that makes all three equations a true statement. A Graphical Representation Whereas linear equations in two variables are graphed as lines in the two-dimensional Cartesian coordinate plane, linear equations in three variables require three-dimensional space to be graphed.

Solving Systems of Equations. In order to solve for two variables, you need to have two equations. If you only have one equation there are an infinite amount of ordered pairs (x,y) that will work. For example: 4x – 2y = 16 you can have x = 4 and y = 0 (4,0) and (2, -2) and (0, -4) and an infinite amount of others.

Solving Systems with Linear Combinations (“Elimination”): Sometimes solving a system of equations using substitution can be very difficult. For these problems we solve using Linear Combinations (or Elimination). With elimination you solve by eliminating one of the variables. This is accomplished by adding the 2 equations together.

https://info.5y1.org/how-to-solve-systems-of-equations_1_212202.html
Students will use a graphing calculator to solve linear systems of equations in two variables using graphing features and table features. Students will then learn the algebraic methods of substitution and elimination. Students will identify which method is most appropriate for a given system, and use these systems to solve practical applications.
