I’m not 100% sure but I’d say B
For this case we have that if each package of pencils has 10 pencils we have:
![9 * 10 = 90](https://tex.z-dn.net/?f=9%20%2A%2010%20%3D%2090)
Thus, we have a total of 90 pencils.
If Peter lost 18 pencils we have:
![90-18 = 72](https://tex.z-dn.net/?f=90-18%20%3D%2072)
Thus, Peter has 72 pencils left.
Answer:
After losing 18 pencils, Peter has 72 pencils left.
Option A
Y should equal 8. Plug in the variable X. So (-9) times (-2) equals 18. Now the equation is 18-3y=6. 18 plus 6 equals 24. 3y = 24. 24 divided by 3 is 8.
