How to Solve Two-Step Equations (Addition and Multiplication) | Introduction to Algebra

Solving Two-Step Equations (Addition and Multiplication) | Introduction to Algebra In this lesson, we learn how to solve two-step equations that involve both addition and multiplication. Two-step equations require more than one operation to isolate the variable. To solve a two-step equation, we undo the operations in the reverse order using inverse operations. We start by reversing the addition or subtraction, then reverse the multiplication or division. For example, in the equation 2x + 3 = 11, we first subtract 3 from both sides to get 2x = 8. We then divide both sides by 2 to find x = 4. Solving two-step equations helps learners build confidence and prepares them for more advanced algebra topics.
