Write and solve two-step equations in one variable within a mathematical or real-world context, where all terms are rational numbers
Standard:
CC.2.2.7.B.3
Description:
Model and solve real-world and mathematical problems by using and connecting numerical, algebraic, and/or graphical representations.
Standard:
M07.B-E.2.2.1
Description:
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.
Standard:
M07.B-E.2.3.1
Description:
Determine the reasonableness of answer(s) or interpret the solution(s) in the context of the problem.
Standard:
Math.7.EE.4a or 7.EE.B.4.A
Description:
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?
