Unit 6, Lesson 10
Different Options for Solving One Equation
Grade 7
Preparation
Lesson Narrative
The purpose of this lesson is to practice solving equations of the form , and to notice that one of the two ways of solving may be more efficient depending on the numbers in the equation.
- Critique (orally and in writing) a given solution method for an equation of the form $p(x+q)=r$.
- Evaluate (orally) the usefulness of different approaches for solving a given equation of the form $p(x+q)=r$.
- Recognize that there are two common approaches for solving an equation of the form $p(x+q)=r$, i.e., expanding using the distributive property or dividing each side by $p$.
Let’s think about which way is better when we solve equations with parentheses.
