how do i get this answer

Question

The sum of two numbers is
65

and the difference is
13

. What are the numbers?

Answer 1

What level of math are you in ?

If you are in algebra do it this way...

x+y=65

x-y=13

add the equations

2x=78

x=78/2

x=39

39+y=65

y=65-39

y=26

26 and 39 are the numbers

 

If you are in a lower level of math do the following...

65/2=32.5

32+33

31+34

30+35

29+36

28+37

27+38

26+39 and 39-26=13
