Answer:
Using Math.
Step-by-step explanation:
You solve it using math.
See, you should have been more specific with your question, maybe said "What is the answer" not "How do I solve".
But I guess I'll help you out bro
<em>Multiply</em> both sides by 6
that gives you -x>18
then <em>multiply</em> both sides by -1
which means you gotta <u>flip the sign</u>
so final answer is x<-18
Left side: (equation) 2/x=3/90 (multiply them together by cross multiplying. 90x2 divided by 3)
=60
Altogether: 90 (right) + 60 (left) =150 seats in total
I believe it is C, but correct me if I'm wrong.
