Question

The sum of the real numbers x and y is 25. their difference is 13. what is the value of xy?​

Answer 1

Step-by-step explanation:

Given,

x+y=25...(1)

x-y=13......(2)

xy=?

By adding eq 1 and 2

x+y=25

x-y=13

2x=38

x=38/2

x=19

Putting the value of x in eq 1

19+y=25

y=25-19

y=6

Now the value of xy

=19*6

=114

You can verify the value of x and y by putting them in eq 1 and 2

hope it helps.............
