A ballast is actually a weight in the bottom of a ship.
So you need the weight to be balanced to stay afloat if not then you are going to sink so what we had to do is create the same number out of the equations.
The first to boxes you multiply and it equals 10 the other three you add and it equals 10
so the boat stays afloat because it is the same ending number.
Try it out for yourself! Just take away the numbers I put in.
Clever problem solving Jessie! Have a go at the first serious problem. Which one is not solvable?
