PPT-Topic 2: Solving Equations & Inequalities in One Variable

Algebra 1 Solving MultiStep Equations Advanced Special Types of Equations Literal Equations Graphing Inequalities Solving Inequalities Solving Compound Inequalities Absolute Value Equations amp Inequalities. Lesson Objective:. An equation is like a set of scales.. To keep it balanced, whatever you. do to one side you must do to the other.. Use this idea to solve equations like:. 3x + 1 = x + 7 . 2 (3x + 1) = 3 (x – 2). How to Identify Multistep Equations |Combining Terms| How to Solve Multistep Equations | Consecutive Integers | Multistep Inequalities. Learning Objectives. Use the properties of equality to solve multistep equations of one unknown. Substitution and Elimination. Elimination. Arrange the equations in STANDARD FORM. . . Your goal is to find a way to eliminate one of the variables so you can solve a one-variable equation.. . Word Problems Involving One-Step. Equations and Inequalities. 25R. 25L. Word Problems Reflection. Observe,. Question,. Comment . 10/31/11. 10/31/11. Warm-Up:. Warm-Up: Write and solve inequalities. Thirteen plus a number . Subtraction. Lessons 3-1 and 3-2. Addition Property of Inequalities – If any number is ________________ to each side of a true ___________________, the resulting inequality is also ________________.. Notes Part . 13. Systems of Linear Inequalities. Just . like when graphing systems of linear equations, you can graph systems of linear inequalities. . First. , graph both inequalities on the coordinate plane, shading where appropriate. . Mathematical Language. A . solution. of an equation is a number that make the equation true. 3x+2=17. To . solve. an equation means to find all its solution. Two equations are equivalent if they have the same solutions. Lesson 2: One-Step Inequalities. Cornell Notes Header. Topic:. .
