Solving Equations with Variables on Both Sides

Mrs. Yaud teaches students how to solve algebraic equations with variables on both sides. The lesson covers steps for solving such equations, including using the distributive property, simplifying both sides, and isolating variables. Example problems are solved to illustrate these steps, and special cases like no solution or infinitely many solutions are discussed. The lesson concludes with a problem involving the surface area and volume of a rectangular prism.

What is the first step in solving equations with variables on both sides?

• Move constants to one side

• Use the distributive property to eliminate parentheses

• Isolate the variable

• Combine like terms

When simplifying the equation, what should you do after distributing?

• Isolate the variable immediately

• Combine like terms and simplify each side

• None of the above

• Check the solution
