There are seven parts, and each section has a "Things to Remember" box with hints about that particular topic. When solving linear equations, the goal is to determine what value, if any, will produce a true statement when substituted in the original equation. . Add highlights, virtual manipulatives, and more. Dividing by \(0\) is undefined and multiplying both sides by \(0\) results in the equation \(0 = 0\). The solutions are presented graphically on a number line or using interval notation or both. \(\begin{aligned} - \frac { 1 } { 2 } ( 10 x - 2 ) + 3 = 7 ( 1 - 2 x ) & \quad\color{Cerulean} { Distribute } \\ - 5 x + 1 + 3 = 7 - 14 x & \quad\color{Cerulean} { Combine\: same-side\: like\: terms. } There are 3 sections organized by the method for solving:Solve by GraphingSolve using SubstitutionSolve using EliminationWriting and Solving Linear Systems (Word Problems)Graphing Linear InequalitiesGraphing Systems of Linear InequalitiesMost questions are "short response" that ask students to solve and type their answer as an ordered pair. Subtract \(5y\) on both sides so that we can combine the terms involving y on the left side. It is important to first identify the variable, let x represent and state in words what the unknown quantity is. It is helpful to take a minute and choose a few values in and out of the solution set, substitute them into the original inequality, and then verify the results. We'll also see what it takes for an equation to have no solution, or infinite solutions. \(\begin{aligned} 7 x - 2 & = 19 \\ 7 x - 2 \color{Cerulean}{+ 2} & = 19 \color{Cerulean}{+ 2} & & \color{Cerulean}{Add\: 2\: to\: both\: sides.} In this sense, we say that solutions satisfy the equation.. The answer key is automatically generated and is placed on the second page of the file.
