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.. Lesson 2-5. A _______________ _______________ is an equation that involves two or more variables.. literal. equation. Rewriting a Literal Equation:. –. 2x + 5y = 12 Solve for y. .. _________________________________ . Hands-On Algebra with Fractions and Mixed Numbers. Connecting to Algebra . When you hear the word “algebra”, what do you think of?. What are some things you know about algebra?. How might you use algebra in real-life?.

Can’t be a negative number. Examples:. │3│= 3. │-10│= 10. │0│= 0. Absolute Value Equations. Isolate the Absolute Value. 2. X + 2Y = 7 Solve for Y. -X. - X. 2Y = 7 – X. 2. 2. Y = 7 – X. . 2. Y = 7 . -. X. . 2. Y = -½X + 3½. 1. -2X + 3Y = 6 Solve for Y. +2X. + 2X. 3Y = 6 + 2X. We talked extensively about converting rectangular to polar equations. Use the substitutions;. x = . rcos. (. ϴ. ). y = . rsin. (. ϴ. ). x. 2. + y. 2. = r. 2. t. an(. ϴ. ) = y/x. Now, we will take something in terms or r and . By graphing. Definition. 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. . Ch. 1.6. Absolute Value Equations and Inequalities .
