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.

use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.

solve real-world and mathematical problems by writing and solving equations of the form ๐น + ๐ฑ = ๐ฒ and ๐ฑ๐น = ๐ฒ for cases in which ๐ฑ, ๐ฒ and ๐น are all nonnegative rational numbers.

write an inequality of the form ๐น > ๐ค or ๐น < ๐ค to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form ๐น > ๐ค or ๐น < ๐ค have infinitely many solutions; represent solutions of such inequalities on number line diagrams.
