Exercise 76 Page 314

Be careful with the negatives when distributing.

-4/9x+8/3

Practice makes perfect

We will begin simplifying by distributing the - 49 to the terms inside the parentheses.

-4/9(x-6)

Distribute -4/9

-4/9x-(-4/9)6

MoveRightFacToNum

a/c* b = a* b/c

-4/9x-(-24/9)

MultNegNegOnePar

- a(- b)=a* b

-4/9x+24/9

a/b=.a /3./.b /3.

-4/9x+8/3

Since - 49x and 83 are not like terms, the expression cannot be simplified further.
