Solving Complicated Linear Equations

The video tutorial explains how to solve linear equations with additional terms and negative numbers. It begins with a simple equation, 3x + 5 = 17, and demonstrates a visual method to understand the process. The tutorial then provides a step-by-step solution, emphasizing the importance of maintaining equality by performing the same operations on both sides. The video concludes with a more complex example, 7x - 2 = -10, involving negative numbers, reinforcing the same principles.

What operation do we perform first to simplify the equation 3x + 5 = 17?

• Add 5 to both sides

• Subtract 5 from both sides

• Multiply both sides by 3
