Question

Find the two numbers whose sum is 29 and whose difference is 5.

Answer 1

Answer:

17 & 12.

Explanation:

It takes more time to add each number separately until you find it, so many look to using x & y to help.

Remember:

Sum = 29

x + y = 29

Difference = 5

x - y = 5

Let's divide by 2 for each equation, to find the answer.

29 + 5 / 2 = 17

29 - 5 / 2 = 12

And there you go!

P.S I had to get some online help for this one, but I learned how to do it now too. :)

Answer 2

Answer:

17 and 12

Step-by-step explanation:

x+y=29

x-y=5

2x=34

x=34/2

x=17

17+y=29

29-17=y

12=y

17-y=5

17-5=y

12=y
