Question

The sum of two numbers is 36. Their difference is 24. What are the numbers?

Answer 1

`30` and `6`

Explanation:

Let the numbers be `x` and `y`. Then

`x+y = 36`
`x-y=24`

Adding the two equations together gives

`2x=60`

`:.x=30`

Substituting this back into either of the equations gives `y=6`
