Solving Two-Step Equations with Fractions
Solving Two-Step Equations with Fractions is a Grade 7 math skill from Big Ideas Math, Course 2, covering Expressions and Equations. To solve two-step equations containing fractions, we can eliminate the fractions first by multiplying both sides by the least common denominator (LCD). This creates an equivalent equation without fractions that follows the standard two-step solving process. Explanation When solving two-step equations with fractions, clearing the fractions first makes the problem much easier to handle. By multiplying every term by the LCD, we eliminate all denominators and create a standard two-step equation.
