Exercise 61 Page 320

Remember, only like terms can be combined.

- 6y - 5

Practice makes perfect

The first step in simplifying this expression is to identify which, if any, terms can be combined. Remember, only like terms — constant terms or terms with the same variable — can be combined. 9 - 6y - 14 In this case, we have one y-term and two constants. Only the constants can be combined, so to simplify the expression we will rearrange it according to the Commutative Property of Addition and then combine like terms.

9 - 6y - 14
