Big Ideas: Linear equations in one variable may have infinite solutions. Linear equations with infinite solutions simplify to the form a = a, where a is any real number. This lesson requires students to translate words to expressions, combine expressions, and finally build and solve an equation. The equation simplifies to the form a = a. Students will recognize that, when substituted for a, any real number will make the statement true. Therefore, the equation has an infinite number of solutions. Vocabulary: infinite
