Exercise 10 Page 723

Be careful with negatives when distributing.

2x-10

Practice makes perfect

We will begin simplifying by distributing the -2 to the terms inside the parentheses.

- 2(5-x)

Distribute - 2

(- 2)5 -(-2)x

(- a)b = - ab

- 10 -(-2)x

a-(- b)=a+b

- 10 +2x

2x-10

Since 2x and - 10 are not like terms, the expression cannot be simplified any further.
