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.

Front

How do you combine like terms?

Back

To combine like terms, add or subtract their coefficients while keeping the variable part the same. For example, 3x + 5x = 8x.

Front

What is the first step in adding multiple expressions?

Back

The first step is to group all the like terms together from each expression.

Front

Solve: (y - 6x + 5) + (6y - 5x + 3) + (5y + 2x - 7)

Back

12y - 9x + 1

Front

Solve: (3w - 8) + (-6w - 4)

Back

-3w - 12

Front

Solve: (7k + 9) + (4k - 3)

Back

11k + 6

Front

Solve: (3x + 15) + (4x + 13)

Back

7x + 28

What is the result of adding (y + 2x + 5) + (3y - 3x + 1)?

Back

4y - x + 6
