North Carolina Standard Course of Study
NC.7.EE. Expressions and Equations
Solve real-world and mathematical problems using numerical and algebraic expressions, equations, and inequalities.
NC.7.EE.4. Use variables to represent quantities to solve real-world or mathematical problems.
NC.7.EE.4.a. Construct equations to solve problems by reasoning about the quantities.
NC.7.EE.4.a.2. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach.
NC.7.EE.4.b. Construct inequalities to solve problems by reasoning about the quantities.
NC.7.EE.4.b.1. Fluently solve multi-step inequalities with the variable on one side, including those generated by word problems.
NC.7.EE.4.b.2. Compare an algebraic solution process for equations and an algebraic solution process for inequalities.
NC.7.EE.4.b.3. Graph the solution set of the inequality and interpret in context.
