x=2
Step-by-step explanation:
i took the quiz
I drew these, as I just did these in math not too long ago. When I shaded it, it was in all four quadrants.
For this question you can say:
-8 -11q = -9q +6
so now you can add +9q on both sides and +8 on both sides of the equation:
-11q + 9q = 8 + 6
-2q = 14
q = 14/-2
q = -7 :)))
I hope this is helpful
have a nice day
Answer:
Step-by-step explanation:

so for x: 15-8 = 7
for y: 9-3 = 6
so the final answer is:
