# Variables in Equations

Solving real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers. Understanding 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? Using substitution to determine whether a given number in a specified set makes an equation or inequality true.
