Exercise 62 Page 320

Remember, only like terms can be combined.

- 6d - 7

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. 2d - 7 - 8d In this case, we have two d-terms and one constant. Only the d-terms can be combined, so to simplify the expression we will rearrange it according to the Commutative Property of Addition and then combine like terms.
