Is there any more information, such as the value of q? Otherwise the sum of q and 8 is q + 8 because "sum" indicates addition.
Step-by-step explanation:
12g=12(2/3g-1)+ 11
12g=24/3g-12+11
12g-24/3g=-1
12g-8g=-1
4g=-1
g=-1/4
-6 it is just the opposite of the number. So a positive would be a negative and a negative a positive. So the answer to your question is -6.
15\x and 80\100
15 times 100=1500
1500=8x
then you divide 1500 by 80 so x is by itself
x=18.75
