Write and Solve Equations with Variables on Both Sides

Front

What is an equation with variables on both sides?

Back

An equation that contains variables on both the left and right sides, requiring manipulation to isolate the variable.

Front

How do you solve an equation with variables on both sides?

Back

1. Move all terms involving the variable to one side of the equation. 2. Move constant terms to the other side. 3. Simplify and solve for the variable.

What is the first step in solving the equation 15 + 2.5x = 10 + 3x?

Back

Subtract 2.5x from both sides to get 15 = 10 + 0.5x.

Front

How do you interpret the solution to an equation in a real-world context?

Back

The solution represents the specific value (e.g., number of rides, games, weeks) at which two scenarios become equal.

Front

What is the role of constants in equations like 15 + 2.5x = 10 + 3x?

Back

Constants represent fixed values that do not change, such as entry fees or initial amounts.
