Solving Multi-Step Equations with Variables on Both Sides

The video tutorial covers solving multi-step equations with variables on both sides, incorporating the distributive property, combining like terms, and moving variables. It introduces a mnemonic, 'Don't Call Me After Midnight,' to remember the steps: Distribute, Combine, Move, Add/Subtract, Multiply/Divide. The tutorial includes six examples demonstrating these techniques, addressing various complexities such as invisible and decimal coefficients, and rewriting equations for simplicity.

What is the first step in solving a multi-step equation with variables on both sides?

• Combine like terms

• Distribute if there are parentheses

• Move the variables to the same side

• Add or subtract to remove the constant

What does the 'C' in the phrase 'Don't Call Me After Midnight' stand for?

• Coefficient

• Constant

• Call

• Combine like terms

In Example 1, what is the result after distributing 2 on the left side?

• 2x - 2

• 2x + 2

• 2x - 1

In Example 1, what is the value of x after solving the equation?

• 2

• 1

• 14

• 12

In Example 2, what is the simplified form of the left side after distributing 5?
