Answer:
2/7 of the waffles did not have blueberries or chocolate chips.
Step-by-step explanation:
So first, it says 4/7 were blueberry, and 1/7 were chocolate chip. When you add them two you get 5/7. The denominator is 7, so subtract 7 from 5 and you get 2, 2/7. 2/7 of the waffles did not have blueberries or chocolate chips.

Your answer would be x=-10.5
First distribute -2/3 to 3x and -9
-2x+6=15
Then subtract 6 from both sides 
-2x=9
Divide both sides by -2
x=-4.5
