Combining Like Terms

Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms, while 3x and 4y are not.

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, 2x + 3x = 5x.

Front

Simplify: 5p + 7y + 2t - 3p + 4y

Back

2p + 11y + 2t

Front

Simplify: x + 3x + 6x + x

Back

11x

Front

Simplify: 5e + 7e - 10e + 9e

Back

11e

Front

Simplify: 7t - 3t + t - 3t

Back

2t

Front

Simplify: 10d - 3d + 2e + 4d

Back

11d + 2e

Front

What is the coefficient in the term 4x?

Back

The coefficient is 4.

Front

What is the constant term in the expression 3x + 5 - 2x?

Back

The constant term is 5.

Front

Can you combine 2x and 3y? Why or why not?

Back

No, because they are not like terms; they have different variables.
