Exercise 83 Page 213

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)

Distribute - 3

(-3)(- 6y)-(- 3)4z

MultNegNegTwoPar

(- a)(- b)=a* b

18y-(- 3)4z

MultNegNegOnePar

- a(- b)=a* b

18y+12z

Since 18y and 12z are not like terms, the expression cannot be simplified further.
