The Truth Value of an Equation
The Truth Value of an Equation is a skill on Pengi from Lesson 1: Equations in One Variable in Illustrative Mathematics, Grade 6.
Key Concepts
Property An equation is a statement that two mathematical expressions are equal. This statement can be either true (if the values on both sides of the equal sign are the same) or false (if the values are different). For an equation with a variable, the equation is true only for specific values of that variable, which are called solutions.
Examples The equation $5 + 3 = 8$ is a true statement because both sides equal 8. The equation $4 \times 3 = 10$ is a false statement because the left side equals 12, and $12 \neq 10$. For the equation $x + 5 = 9$, the statement is true only when $x = 4$. If you substitute any other value for $x$, the statement becomes false.
Explanation Think of an equation as a question: "Are the two sides really equal?" If they are, the equation is true. If they are not, the equation is false. When an equation includes a variable, solving the equation means finding the specific value for the variable that makes the equation a true statement.
