AIM: How can we write and solve equations?
HW: Writing Equations Worksheet #1-4
a) State the inverse (operation included) of each term:
-3x 5 2n
b) What do the words "twice" and "double" mean?
Classwork: We worked towards the highest level of equation solving today-- writing equations to solve word problems. After working through a problem about the cost of a guitar, we devised the following process for approaching these types of problems:
1. Define a variable (which is what you are trying to figure out).
2. Write an equation using the variable and key words and numbers from the word problem.
3. Solve the equation using inverse operations and the rules of equality.
Please use these steps when you complete your homework. These apply for one AND two-step equations.
