Conveyor A moves 10009\displaystyle \frac{1000}{9}91000 boxes in 1 minute Conveyor B moves 10007\displaystyle \frac{1000}{7}71000 boxes in 1 minute Conveyor C moves 1000x\displaystyle \frac{1000}{x}x1000 in 1 minute. All together they move 10003\displaystyle \frac{1000}{3}31000 in 1 minute. Put it all together and solve for x.
