Fluently solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers.
Patterns, Functions, and Algebraic Structures
- Use critical thinking to recognize problematic aspects of situations, create mathematical models, and present and defend solutions
Equations and expressions model quantitative relationships and phenomena
Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.
