Exercise 82 Page 288

Be careful of negatives when distributing.

18y+12z

Practice makes perfect
We will begin simplifying by distributing the -3 to the terms inside the parentheses.
- 3(- 6y-4z)
(-3)(- 6y)-(- 3)4z
18y-(- 3)4z
18y+12z
Since 18y and 12z are not like terms, the expression cannot be simplified further.
