Explain how to write an equivalent expression by combining like terms. w + 10 + w – 4

Sample Response:  To combine like terms, add the variable terms together and then add the constants together. When you combine the variable terms, you have 1w + 1w, which is 2w. When you combine the constants, you have 10 – 4, which is 6. The equivalent expression is 2w + 6.
