A shipping container will be used to transport several 50-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 25000 kilograms. Other shipments weighing 11000 kilograms have already been loaded into the container. Write and solve an inequality which can be used to determine x, the number of 50-kilogram crates that can be loaded into the shipping container.
inequality:
x=
