PPT-Solving Literal Equations and Formulas

Lesson 25 A is an equation that involves two or more variables literal equation Rewriting a Literal Equation 2x 5y 12 Solve for y . e Ax where is vector is a linear function of ie By where is then is a linear function of and By BA so matrix multiplication corresponds to composition of linear functions ie linear functions of linear functions of some variables Linear Equations Notes. Literal. means straight forward or factual. It is the dictionary meaning of the word.. Denotation:. the explicit or direct meaning or set of meanings of a word or expression, as distinguished from the ideas or meanings associated with it or suggested by it.. 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). Get started. Imagine that Excel is open and you’re looking at the “Entertainment” section of a household expense budget.. Cell C6 in the worksheet is empty; the amount spent for CDs in February hasn’t been entered yet.. 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 “ . Problem 1. There are 25 toys in a playground. . The toys are either bicycles (2 wheels) or tricycles (3 wheels). . In total in the playground there are 61 wheels. . How many bicycles are in the playground?. 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. ™.
