Front

Definition: One-Step Equation

Back

An equation that can be solved in one step by performing the same operation on both sides.

Front

Example of a One-Step Equation: x + 5 = 10

Back

x = 5

Front

Definition: Isolate the variable

Back

To get the variable alone on one side of the equation.

Front

Example of isolating a variable: 3x = 12

Back

x = 4 (divide both sides by 3)

Front

Definition: Inverse Operation

Back

An operation that reverses the effect of another operation (e.g., addition and subtraction).
