Step-by-step explanation:
If J can paint a room in 3 hours, in 1 hour she gets 
of the job done.
If A can paint a room in 4 hours, in 1 hour she gets 
of the job done. We need to find out how long it takes them if they paint together. The equation for this is:
where x is the number of hours it takes them to get the job done together. Multiply everything through by 12x to get
4x + 3x = 12 so
7x = 12 and
x = 1.7 hours to get the room painted together.
