Solve Two-Step Equations

TEKS Math: 7.11.A

(A) Model and solve one-variable, two-step equations and inequalities

AU Math: ACMNA194

(Y8) Solve linear equations using algebraic and graphical techniques. Verify solutions by substitution (ACMNA194)

CCSS Math: 7.EE.4

7.EE.4 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.

7.EE.4.A

7.EE.4.A 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. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. For example, the perimeter of a rectangle is 54 cm. Its length is 6 cm. What is its width?

This expressions and equations lesson covers how to solve two-step equations. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students will isolate the term with the variable using inverse operations, and then solve for the variable. Finally, they will check and interpret the solution.
