Solve systems of two linear equations in two variables and estimate solutions by graphing the equations. Simple cases may be done by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6. Solve real-world and mathematical problems leading to two linear equations in two variables.

Combine the first two equations and eliminate y (any of the three variables can be chosen, y is chosen for ease): 4x + z = 5. Now, just solve for z: z = 5 – 4x. This time, eliminate x from the first two equations:-4y – 7z = -1. 4y + 7z = 1. Once again, solve for z: . Putting these two equations together we get the solution of the system to be.

The graphical method is applicable to solve the LPP involving two decision variables x1, and x2, we usually take these decision variables as x, y instead of x1, x2. To solve an LP, the graphical method includes two major steps. a) The determination of the solution space that defines the feasible solution.
Systems of Linear Equations: Two Variables | College Algebra
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.
