Solving Two Step Equations
Equations can be tricky, and
solving two step equations is an important step beyond solving equations in one step. Solving two-step equations will help introduce students to solving equations in multiple steps, a skill necessary in Algebra I and II. To solve these types of equations, we use additive and multiplicative inverses to isolate and solve for the variable.
Solving Two Step Equations: The Basics
This video explains how to solve basic two step equations.
Examples:
1. 2x + 3 = 9
2. 5x - 8 = 22
3. 9 - 2x = 23
4. -11 = 4x - 43
5. -15 = 5 - 5x
