Modeling - 2x + 3 = 11. =. Each one has 4 squares, so 4 is your answer!. Solving 2-Step Equations. Algebraic equations are solved backwards, so do the OPPOSITE math!. Since there are more than 1 steps to do you must follow the Order of Operations…but BACKWARDS!!!. Multiplication . Equations. 3-3 Solving . Multiplication . Equations. Solve. Solution. GOAL. Find the value of the variable that makes the. equation TRUE.. The value that makes the equation true.. To isolate the variable (have the variable on one. 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.. . 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! . If you read from left to right . 10 . “is greater than “ . 5. . X. If you read from right to left . 5. . “is less than “ . 10. . X. If you read from left to right . 5. . “is less than “ . Part 1. -9 +2X = 5X + 12. -2X. -2X. -9 = . 3X. + 12. -12. -12. -21 = 3X. 3. 3. X = -7. -5 – X = 4X - 15. 1. +1X. +1X. -5 = 5X - 15. +15. +15. 10 = 5X. 5. 5. X = 2. 12X + 3 = 4X + 27 - X. 12X + 3 = . 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. _____________________________________________________________. Algebra 1 – Solving . Equations - Math is Hip. ™. Prerequisite Skills Needed:. - . Order of Operations. - Add/Subtract & Multiply/Divide . Numbers/Cronnelly. 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! . Classifying Polygons. Students . will be able . to:. Identify the 2-dimensional shapes based on their properties.. Key Vocabulary. Polygons. Triangles. Quadrilaterals. Pentagons and Hexagons. Other Polygons. Examples:. . 1). . . x 3 = 15. . 2) p – 5 = 20. 3) 2d = 16. 4). . = 24. . Multi-Step Equations. Examples—. 5). 2p 15 = 29. 6). 14 – 3n = -10. 7). 27 = -9(y 5). 8). 7a – 3a 2a – a = 16.
