### 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.

How to solve two-step equations?

1. Add or subtract in order to isolate the variable term.

2. Multiply or divide to solve for the variable.

3. Check all possible solutions.

Remember to maintain inequality, we must perform the same operation to both sides of the equation.

**Ex: Solve a Two-Step Equation with Decimals**

This video provides an example of solving a two-step equation with decimals.

Example:

0.24x + 16.4 = -1.48

**Solving Two Step Equations: A Summary**

This video explains how to solve two step equations.

Examples:

1. 2x + 3 = 25

2. x/4 - 2 = -5

3. 4 - 2x = 10

4. 4 = 6 - x/3

5. 4.3 = 1.5x - 5

6. x/3 - 3/4 = 1/6
