Simultaneous Occasions | Summer Holidays | Rabbits and Chickens | Rail Weigh

There are also a series of randomly-generated, self-marking simultaneous equations exercises you clould try:

| Level 1 | Level 2 | Level 3 | Level 4 | Level 5 | Level 6 |

There are solutions to this exercise but they are only available to those who have a Transum Subscription.
