Section 5.4 Study Materials
Equations and Expressions
An equation is a mathematical statement that two expressions are equal. For example, = 7 is an equation. Note: An equation contains an equal sign, “ = ”; an expression does not contain an equal sign. We solve equations, and we simplify expressions.

Equations
In this section, we will learn how to solve linear equations in one variable; such an equation can have no solution, exactly one solution, or infinitely many solutions. In this course, we will only consider linear equations in one variable that have exactly one solution. In general, solving an equation involves finding all numbers that can replace the variable to make the equation a true statement.

10. Addition Property of Equality
Section 5.4 Study Materials
Addition Property of Equality
Adding the same expression to both sides of an equation will produce an equivalent equation. Therefore, adding the same expression to both sides of an equation will not change the equation’s solution.
