Standard 7.EE.B.4a - Use the properties of addition and multiplication to solve multi operator variable expressions.
Included Skills: Algebra, Number Properties
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?
