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

Answer:

Two numbers are 9 and 8

Step-by-step 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
