The question in English

Find two numbers whose sum is 45 and whose subtraction is 21

Let

x-------> first number (greater number)

y------> second number

we know that

`x+y=45` ------> equation A

`x-y=21` ------> equation B

Adds equation A and equation B

`x+x=45+21`

`2x=66`

`x=33`

Find the value of y

`x+y=45`

`33+y=45`

`y=12`

The two number are
`33` and
`12`
