Unit 5 – Systems of Linear Equations and Inequalities
This unit begins by ensuring that students understand that solutions to equations are points that make the equation true, while solutions to systems make all equations (or inequalities) true. Graphical and substitution methods for solving systems are reviewed before the development of the Elimination Method. Modeling with systems of equations and inequalities is stressed. Finally, we develop the idea of using graphs to help solve equations.

ADDITIONAL COMPONENTS INCLUDED:
(1) Links to Instructional Videos: Links to videos of each lesson in the unit are included. Videos were created by fellow teachers for their students using the guided notes and shared in March 2020 when schools closed with no notice. Please watch through first before sharing with your students. Many teachers still use these in emergency substitute situations.
(2) Editable Assessments: Editable versions of each quiz and the unit test are included. PowerPoint is required to edit these files. Individual problems can be changed to create multiple versions of the assessment. The layout of the assessment itself is not editable. If your Equation Editor is incompatible with mine (I use MathType), simply delete my equation and insert your own.
(3) Google Slides Version of the PDF: The second page of the Video links document contains a link to a Google Slides version of the PDF. Each page is set to the background in Google Slides. There are no text boxes; this is the PDF in Google Slides. I am unable to do text boxes at this time but hope this saves you a step if you wish to use it in Slides instead!

1. Sort to line up the variable and equal signs. 2. Multiply one or both equations by a constant to create the additive inverse of the variable. 3. add or subtract one equation eliminate one of the variables. 4. Solve for variables that remain. 5. substitute new value back into the equation to get the other variable. 6.
Solving a System of Equations by Elimination. a method for solving a system of equations where you add the two equations together and cancel one of the variables. Also known as Linear Combination. System of Inequalities. a set of inequalities with the same variables. The solution is the set of all points that fall in the overlapping region.
A system of equations that has no solution. The graphs of the equations never intersect. part of a coordinate plane being used to represent the solution set for an inequality in two-variables. Study with Quizlet and memorize flashcards containing terms like boundary line, bounded region, constraints and more.
Example Solve the system of equations 2(y −3) = x+3y x+2 = 3−y First, write both equations in the form ax+by = c. First Equation: 2(y −3) = x+3y 2y −6 = x+3y −x−y = 6 Second Equation: x+2 = 3−y x+y = 1 The system of equations is now: −x−y = 6 x+y = 1 Solve with the elimination method. Add the two equations. 0 = 7 This is never ...

5.1: Prelude to Systems of Equations and Inequalities. In this chapter, we will investigate matrices and their inverses, and various ways to use matrices to solve systems of equations. First, however, we will study systems of equations on their own: linear and nonlinear, and then partial fractions. We will not be breaking any secret codes here ...

By solving the system by substitution, we got the solutions: x = 2/3, y = 8/3. Solving the system of equations: we need to solve problem number 5, so let's do that. Here we have the system of equations: y = x + 2. 3x + 3y = 6. To solve it by substitution, we need to isolate one of the variables in one of the equations and then replace that in ...

The subject of the question is Systems of Equations & Inequalities in Mathematics, specifically focusing on solving systems through substitution. Given two linear equations in the form of y = b + mx, you can find a solution by isolating a variable (in this example, In A) in one of the equations and substituting it into the other equation.
Answer: (x, y) = (-3, -5) Step-by-step explanation: You want to solve the given system of equations by elimination.. 2x -3y = 9-5x -3y = 30; Elimination. To eliminate a variable from the equations, we need to add them in such a way that the coefficients for one of the variables have a total of zero.
elimination system. a method used to solve systems of equations in which one variable is eliminated by adding or subtracting two equations of the system. Substitution. An algebraic model that can be used to find the exact solution of a system of equations. Unit 5: Systems of Equations and Inequalities. solution set.
system of linear inequalities. a set of two or more linear inequalities. solution system of inequalities. the common shaded region between all the inequalities in the system. Study with Quizlet and memorize flashcards containing terms like System of equations, Solution of a system, Intersection point and more.
To solve this system of equations by elimination, we need to eliminate one of the variables (either x or y) by adding or subtracting the equations. In this case, we can eliminate x by multiplying the first equation by 2 and subtracting it from the second equation: 2x - 6y = 12 (original second equation)
