Front

How do you combine like terms?

Back

To combine like terms, add or subtract the coefficients of the terms that have the same variable. For example, 3x + 2x = (3 + 2)x = 5x.

Front

Simplify the expression: 3x + 2x

Back

5x

Front

Combine like terms: 3x + 2x + 3y - 7y

Back

5x - 4y

Front

Simplify the expression: 3 + 5x + 8 - 2x

Back

11 + 3x

Front

Combine like terms: -2x + 11 + 6x

Back

4x + 11

Front

Simplify the expression: 3x - 5x

Back

-2x

Front

What is the coefficient in the term 7x?

Back

The coefficient is 7.

Front

What happens when you combine 4y and -2y?

Back

4y + (-2y) = 2y.
