Target We can solve for the unknown in singlestep equations By Shelly Jamison Solve For The Unknown Quick Check 1 What is the first thing you should do when solving for an unknown in a problems so you know how to start solving. www.invo.org.uk www.invo.org.uk www.invo.org.uk www.invo.org.uk www.invo.org.uk www.invo.org.uk www.invo.org.uk This guide was published in February 2002 and revised in August 2006 under the title: A 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). using Elimination. Steps:. 1. Place both equations in Standard Form, A. x . + B. y . = C.. 2. Determine which variable to eliminate with Addition or Subtraction.. 3. Solve for the variable left.. Rational Numbers. Lesson 6.2.3. Please. The topic of today’s. lesson is…. fractions and decimals. Admit it… . You can’t stand working with decimals.. You despise fractions even more, don’t you! . Day . 3. Mathematicians at Work . C- Accountable Talk (Whisper). H- Help Sign. A- Math Workshop.

A system of linear equations, aka linear system, consists of two or more linear equations with the same variables.. x + 2y = 7. 3x – 2y = 5. The solution. The solution of a system of linear equations is the ordered pair that satisfies each equation in the system. . Equations for uniform acceleration. Where. s. is displacement (m). v. is the final velocity (m s. -1. ). u . is the initial velocity (m s. -1. ). a. is the acceleration (m s. -2. ). Numbers/Cronnelly. Lesson 6.2.3. Please.
