What are like terms in an expression?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and -9x are like terms because they both contain the variable x.

Front

Combine the like terms: 3x + 7 - 9x + 24y + 2x²

Back

-6x + 7 + 24y + 2x²

What is the result of combining like terms: n - 10 + 9n - 3?

Back

10n - 13

Front

What does it mean for an equation to have infinite solutions?

Back

An equation has infinite solutions when any value of the variable satisfies the equation, meaning both sides are equivalent for all values.
