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, 2a + 3a = 5a.

Front

Simplify: 5a + 2b - 3a + 4

Back

2a + 2b + 4

Front

Simplify: 4x + 3 + 7x

Back

11x + 3

Front

Simplify: 2r + 2 + 5r + 2 + r

Back

8r + 4

Front

Simplify: -2x + 11 + 6x

Back

4x + 11

Front

Simplify: 3y + 4y - 2y + 1

Back

5y + 1

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 3x + 5, the number 5 is a constant term.
