Front

Definition: Equation

Back

A mathematical statement that asserts the equality of two expressions.

Front

Definition: Solving an equation

Back

Finding the value of the variable that makes the equation true.

Front

Principle: Isolate the variable

Back

To solve an equation, rearrange it to get the variable on one side and constants on the other.

Front

Example: If 3x + 5 = 20, what is x?

Back

x = 5 (Subtract 5 from both sides, then divide by 3.)
