Solving Equations with Variables on Both Sides

This video tutorial covers solving equations with variables on both sides. It explains the parts of an equation, including variables, coefficients, and constants. The tutorial walks through three steps to solve such equations: distributing and combining like terms, collecting variable and constant terms, and isolating the variable. Several example problems are solved, and a real-world application is discussed to reinforce the concepts. The video concludes with a summary of the key points.

What represents an unknown value in an equation?

• Constant

• Equation

• Coefficient
