6.EE.5:
Expressions And Equations
Reason About And Solve One-Variable Equations And Inequalities.
Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true.
6.EE.8:
Expressions And Equations
Reason About And Solve One-Variable Equations And Inequalities.
Write an inequality of the form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form x > c or x < c have infinitely many solutions; represent solutions of such inequalities on number line diagrams.
