Front

What are variables in an equation?

Back

Variables are symbols (like x or n) that represent unknown values in an equation.

Front

What does it mean to have variables on both sides of an equation?

Back

It means that the variable appears in expressions on both sides of the equal sign.

Front

How do you isolate a variable in an equation?

Back

To isolate a variable, you perform operations to get the variable alone on one side of the equation.

Front

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

Back

The first step is to simplify both sides of the equation if necessary.

Front

How do you combine like terms in an equation?

Back
