Look for a notetaking strategy at the beginning of each chapter as well as helpful for tests. Your sister can get $30 per day for selling clothes at the market. Notice how the value on each side of the = sign is the same for each equation: 5 + 7 = 8 + 4 19 − 7 = 12 42 = 3 • 14 If an equation contains a variable, and the variable is replaced by a value 2. 320 Chapter 6 Solving Linear Inequalities Variables on Both Sides Solve 5p 7 6p. 11d + 10 = 6d 5. 98 t 18 20. Flashcards. 4 Solving Equations With Variables on Both Sides Goals: Collect variables on one side of an equation and use equations to solve real-life problems. Each word problem should be different, but give the same equation to solve. 4(3r 2) 4 12r 14. 1) 3x – 2y + 2 = 0. Get the variable on one side of the equation by itself. 2-4 Solving Equations with Variables on Both Sides LESSON 48 2 5 Possible answers: add 3x to each side, add 15x to each side Possible answers: add 3x to each side, add 7x to each side Possible answers: add 4x to each side, add 10x to each side AA1CRB07C02L04. Variable on Both Sides Solving Equations With Like Terms. Solving Equations With Variables On Both Sides Worksheets for 6th Grade and 7th Grade Step 4: Simplify both expressions on each side of the equal sign Subtract one variable from both sides (if needed) Solve equation using inverse operations Check your answer 2x + 10 + 3x = 20 5x + 10 = 20 - 10 - 10 5x = 10 5 5 x = 2 6y + 12 = -2y + (-20) +2y +2y 8y + 12 = -20 - 12 - 12 8y = -32 y = -4 2(2 + 5) + 3(2) = 20 20 = 20 6(-4)+ 12 = -2(-4 + 10)-12 = -12 Reteach Solving Linear Equations and Inequalities (continued) Name Date Class 2-1 LESSON The symbol means that –3 is included in the graph. 85 plus $32 a room. SEE EXAMPLES 1 AND 2 16. ABC AUTO RENTAL Cost per Cost er Day $25 $0. 7 7. Nancy’s plant made four fewer than twice the number produced by Jim’s plant. Content Learning Outcome: Students will learn how to think about and connect mathematics text, examples, and exercises to determine when to use algebraic solutions to solve systems of equations. This will remove the b from the right side of the equation. 3 does not equal 5. 4) x – 4y = 8. 7) -1. must be driven for each option to cost the same for one day. 92 = −4(2r − 5) 23.
