Question

What two numbers have a sum of 17 and difference of 1

Answer 1

9 and 8  they add up to 17 and have a difference on 1

Answer 2

Two numbers are 9 and 8

Explanation:

two numbers have a sum of 17 and difference of 1

LEts x and y be the two numbers

sum is 17, so
`x+y=17`

Difference is 1, so
`x-y=1`

Now we solve for x and y, Add both equations

`x+y=17`

`x-y=1`

-------------------------

`2x= 18`

Divide both sides by 2

x= 9

Now we plug in x and find out y

`x+y=17`

`9+y=17`, subtract 9 on both sides

`y=8`

Two numbers are 9 and 8
