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 + 5x = (3 + 5)x = 8x.

Front

Simplify: 6x + 1 + 7x

Back

13x + 1

Front

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

Back

2a + 2b + 4

Front

Simplify: -2x + 11 + 6x

Back

4x + 11

Front

Simplify: -4x - 10x

Back

-14x

Front

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

Back

8r

Front

What is the coefficient in the term 7x?

Back

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

Front

What happens when you combine unlike terms?

Back

Unlike terms cannot be combined. They remain separate in an expression.

Front

What is the result of combining 3x and 4y?

Back

3x + 4y (they cannot be combined because they are unlike terms).
