Division rate of X-cell = x cells/hour
Division rate of Y-cell = y cells/hour.
Starting quantity for X-cells in container A=10,000
Starting quantity for Y-cells in container B=10,000
After one hour, quantity of X-cells in container A=10,000x
After one hour, quantity of Y-cells in container B=10,000y
Also, after another hour, quantity of X-cells in container A=(10,000x)x
after another hour, quantity of Y-cells in container B=(10,000y)y
Substituting for y in (2)
Division rate of X-cell = 7 cells/hour
