Algebraic Equations
Writing algebraic equations and applying the same to solve problems for real-world situations. Comparing algebraic solutions to arithmetic solutions. Identifying lines in graphs that correspond to equations of the form px + q = r. Evaluating the process of problem solving that use algebraic equations of single variable.
Mapped to CCSS Section# 7.EE.B.4a
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?
