Answer:
Step-by-step explanation:
The starting equation is
12-(3x+13)=0
First add 3x+13 to both sides so that only 12 is on the left
12=3x+13
now subtract 13 from both sides to isolate your variable
-1=3x
Finally divide both sides by 3 to get your final answer
x=-1/3
Just subtract 9:00-2:30 so your answer should 6 hours and 30 minutes or 6 1/2 hours
