: How can we use the properties of equality to solve equations?AIM Unit 4 ACE #14-16, p.71-72HW:Do Now:Use the concept of equality to solve for the missing value that would make the statement true. 3x + 4 = 13 Ans. x=3 We equated solving equations keeping a balance beam balanced. We used this comparison (along with the coins and pouch situation from earlier) to come up with the following strategies and techniques.Classwork:When solving an equation, remember: -Isolate the variable -Use inverse operations -What you do to one side, make sure that you do to the other (You must keep the scale balanced!!!) We began with simple one step equations as a review and transitioned to more difficult problems involving fractions and integers. We will soon be solving two step equations! :ResourcesEquation Solving SongIf you want to solve equations, here is how. Read them with their operations, do it now. Then UNDO them every time By directions in this rhyme. DO THE OPPOSITE, that’s what the rules allow. If you read “MINUS,” then to solve them you must ADD. If you say “PLUS” you must SUBTRACT or you’ll be sad. Multiply will get undone By DIVIDING every one. And divide gets MULTIPLIED, or answer’s bad. Oh, equations must stay balanced to be true. WHAT YOU DO TO ONE SIDE YOU MUST DO TO TWO. And to solve for the unknown You must get it all alone Using every single trick you know to do. ## Leave a Reply. |
