7. The Distributive Property
Continue to next subchapter

Exercise 35 Page 50

Rewrite the negative sign as - 1, then use the Distributive Property.

- 9+7c

Practice makes perfect
To simplify the expression, we will use the Distributive Property to multiply the terms on the inside of the parentheses by the term on the outside. For this specific exercise, the negative sign can be thought of as - 1.
-(9-7c)
- 1 (9-7c)
-1(9)-1(-7c)
-1(9) + 7c
-9+7c
As -9 and 7c are not like terms, we cannot simplify the expression further.
