Exercise 79 Page 288

Be careful of negatives when distributing.

8y-12z

Practice makes perfect
We will begin simplifying by distributing the - 4 to the terms inside the parentheses.
- 4(- 2y+3z)
(-4)(- 2y)+(- 4)3z
8y+(- 4)3z
8y-12z
Since 8y and - 12z are not like terms, the expression cannot be simplified further.
