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.

This video provides examples of solving two step linear equations involving decimals.
Examples:
0.3x - 2.16 = 9.9
x/2.1 + 4.93 = 10.45
This video provides an example of solving a two-step equation with decimals.
Example:
0.24x + 16.4 = -1.48
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
