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, 3x + 2x = 5x.

Simplify by combining like terms: 3x + 2x + 3y - 7y

Back

5x - 4y

Front

Simplify by combining like terms: 2x + 1 + 7x

Back

9x + 1

Front

Simplify by combining like terms: -4x - 10x

Back

-14x

Front

Simplify by combining like terms: -2x + 11 + 6x

Back

4x + 11

Front

Simplify by combining like terms: 3 + 5x + 8 - 2x

Back

11 + 3x

Front

What is the coefficient in the term 7x?

Back

The coefficient is 7, which is the number multiplying the variable x.

Front

What is a constant term?

Back

A constant term is a term that does not contain any variables. For example, in the expression 5x + 3, the number 3 is a constant term.

Front

What happens when you combine like terms with different signs?

Back

When combining like terms with different signs, you subtract the coefficients. For example, 5x - 2x = 3x.
