Solving Linear Equations

COURSE DESCRIPTION

Common Core State Standards for Linear Functions

NC.8.EE.7
Solve real-world and mathematical problems by writing and solving equations and inequalities in one variable.

• Recognize linear equations in one variable as having one solution, infinitely many solutions, or no solutions.
• Solve linear equations and inequalities including multi-step equations and inequalities with the same variable on both sides

21^st Century life skills emphasized:

Communication and collaboration, Communicate Clearly, Critical thinking and problem solving, Information literacy

Simply MeToDo Strategies:

Link to Prior Learning from a prior lesson in the series:

Addition and Subtraction are inverses of each other
Multiplication and Division are inverses of each other

Purpose/Objective of the Lesson:

Students will be able to utilize the inverse properties previously learned to find solutions to an equation.

Unit Essential Question:

How do you isolate a variable to find the solution to the equation?

Key Questions for this lesson: 

• What is the inverse of addition, subtraction, multiplication and division?
• Can you use multiple inverse operation when isolating a variable?
• What is meant by combining like terms?
• Can you provide an example of like terms? Unlike terms?
• Can you combine like terms when the variable is on either side of the equal sign?
• What operation is operations are completed first in solving an equation?
