28 children were riding on the bus. At the bus stop 82 children got on the bus while some got off the bus. Then there were 30 children altogether on the bus. How many more children got on the bus than those that got off?

First, we need to figure out how many children got on the bus. We can do this by looking at the equation: 

new passengers = old passengers + passengers getting on - passengers getting off 

There are 60 old passengers, and we know that the equation equals 84. So, we can set up the equation like this: 

60 + x - y = 84 

We also know that there are more passengers getting on the bus than passengers getting off. So, that means that x is going to be greater than y. We can represent this by saying that x - y is positive. 

Now, we can solve for x. 

60 + x - y = 84 
60 + x - y + y = 84 + y 
60 + x = 84 + y 
x = 84 + y - 60 
x = 24 + y 

Now, we need to figure out how many passengers got off the bus. We can do this by looking at the equation: 

new passengers = old passengers + passengers getting on - passengers getting off 

There are 60 old passengers, and we know that the equation equals 84. So, we can set
